The western financial crisis of 2007-8 was the worst since 1931, yet its immediate repercussions were surprisingly modest. The crisis challenged the foundation stones of the long-dominant neoliberal ideology but it seemed to emerge largely unscathed. The banks were bailed out; hardly any bankers on either side of the Atlantic were prosecuted for their crimes; and the price of their behaviour was duly paid by the taxpayer. Subsequent economic policy, especially in the Anglo-Saxon world, has relied overwhelmingly on monetary policy, especially quantitative easing. It has failed. The western economy has stagnated and is now approaching its lost decade, with no end in sight.

After almost nine years, we are finally beginning to reap the political whirlwind of the financial crisis. But how did neoliberalism manage to survive virtually unscathed for so long? Although it failed the test of the real world, bequeathing the worst economic disaster for seven decades, politically and intellectually it remained the only show in town. Parties of the right, centre and left had all bought into its philosophy, New Labour a classic in point. They knew no other way of thinking or doing: it had become the common sense. It was, as Antonio Gramsci put it, hegemonic. But that hegemony cannot and will not survive the test of the real world.

The first inkling of the wider political consequences was evident in the turn in public opinion against the banks, bankers and business leaders. For decades, they could do no wrong: they were feted as the role models of our age, the default troubleshooters of choice in education, health and seemingly everything else. Now, though, their star was in steep descent, along with that of the political class. The effect of the financial crisis was to undermine faith and trust in the competence of the governing elites. It marked the beginnings of a wider political crisis.

But the causes of this political crisis, glaringly evident on both sides of the Atlantic, are much deeper than simply the financial crisis and the virtually stillborn recovery of the last decade. They go to the heart of the neoliberal project that dates from the late 70s and the political rise of Reagan and Thatcher, and embraced at its core the idea of a global free market in goods, services and capital. The depression-era system of bank regulation was dismantled, in the US in the 1990s and in Britain in 1986, thereby creating the conditions for the 2008 crisis. Equality was scorned, the idea of trickle-down economics lauded, government condemned as a fetter on the market and duly downsized, immigration encouraged, regulation cut to a minimum, taxes reduced and a blind eye turned to corporate evasion.

It should be noted that, by historical standards, the neoliberal era has not had a particularly good track record. The most dynamic period of postwar western growth was that between the end of the war and the early 70s, the era of welfare capitalism and Keynesianism, when the growth rate was double that of the neoliberal period from 1980 to the present.

But by far the most disastrous feature of the neoliberal period has been the huge growth in inequality. Until very recently, this had been virtually ignored. With extraordinary speed, however, it has emerged as one of, if not the most important political issue on both sides of the Atlantic, most dramatically in the US. It is, bar none, the issue that is driving the political discontent that is now engulfing the west. Given the statistical evidence, it is puzzling, shocking even, that it has been disregarded for so long; the explanation can only lie in the sheer extent of the hegemony of neoliberalism and its values.

But now reality has upset the doctrinal apple cart. In the period 1948-1972, every section of the American population experienced very similar and sizable increases in their standard of living; between 1972-2013, the bottom 10% experienced falling real income while the top 10% did far better than everyone else. In the US, the median real income for full-time male workers is now lower than it was four decades ago: the income of the bottom 90% of the population has stagnated for over 30 years.

A not so dissimilar picture is true of the UK. And the problem has grown more serious since the financial crisis. On average, between 65-70% of households in 25 high-income economies experienced stagnant or falling real incomes between 2005 and 2014.

Large sections of the population in both the US and the UK are now in revolt against their lot

The reasons are not difficult to explain. The hyper-globalisation era has been systematically stacked in favour of capital against labour: international trading agreements, drawn up in great secrecy, with business on the inside and the unions and citizens excluded, the Trans-Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (TTIP) being but the latest examples; the politico-legal attack on the unions; the encouragement of large-scale immigration in both the US and Europe that helped to undermine the bargaining power of the domestic workforce; and the failure to retrain displaced workers in any meaningful way.

As Thomas Piketty has shown, in the absence of countervailing pressures, capitalism naturally gravitates towards increasing inequality. In the period between 1945 and the late 70s, Cold War competition was arguably the biggest such constraint. Since the collapse of the Soviet Union, there have been none. As the popular backlash grows increasingly irresistible, however, such a winner-takes-all regime becomes politically unsustainable.

Large sections of the population in both the US and the UK are now in revolt against their lot, as graphically illustrated by the support for Trump and Sanders in the US and the Brexit vote in the UK. This popular revolt is often described, in a somewhat denigratory and dismissive fashion, as populism. Or, as Francis Fukuyama writes in a recent excellent essay in Foreign Affairs: “‘Populism’ is the label that political elites attach to policies supported by ordinary citizens that they don’t like.” Populism is a movement against the status quo. It represents the beginnings of something new, though it is generally much clearer about what it is against than what it is for. It can be progressive or reactionary, but more usually both.

Brexit is a classic example of such populism. It has overturned a fundamental cornerstone of UK policy since the early 1970s. Though ostensibly about Europe, it was in fact about much more: a cri de coeur from those who feel they have lost out and been left behind, whose living standards have stagnated or worse since the 1980s, who feel dislocated by large-scale immigration over which they have no control and who face an increasingly insecure and casualised labour market. Their revolt has paralysed the governing elite, already claimed one prime minister, and left the latest one fumbling around in the dark looking for divine inspiration.

The wave of populism marks the return of class as a central agency in politics, both in the UK and the US. This is particularly remarkable in the US. For many decades, the idea of the “working class” was marginal to American political discourse. Most Americans described themselves as middle class, a reflection of the aspirational pulse at the heart of American society. According to a Gallup poll, in 2000 only 33% of Americans called themselves working class; by 2015 the figure was 48%, almost half the population.

Brexit, too, was primarily a working-class revolt. Hitherto, on both sides of the Atlantic, the agency of class has been in retreat in the face of the emergence of a new range of identities and issues from gender and race to sexual orientation and the environment. The return of class, because of its sheer reach, has the potential, like no other issue, to redefine the political landscape.

The working class belongs to no one: its orientation, far from predetermined, is a function of politics

The re-emergence of class should not be confused with the labour movement. They are not synonymous: this is obvious in the US and increasingly the case in the UK. Indeed, over the last half-century, there has been a growing separation between the two in Britain. The re-emergence of the working class as a political voice in Britain, most notably in the Brexit vote, can best be described as an inchoate expression of resentment and protest, with only a very weak sense of belonging to the labour movement.

Indeed, Ukip has been as important – in the form of immigration and Europe – in shaping its current attitudes as the Labour party. In the United States, both Trump and Sanders have given expression to the working-class revolt, the latter almost as much as the former. The working class belongs to no one: its orientation, far from predetermined, as the left liked to think, is a function of politics.

The neoliberal era is being undermined from two directions. First, if its record of economic growth has never been particularly strong, it is now dismal. Europe is barely larger than it was on the eve of the financial crisis in 2007; the United States has done better but even its growth has been anaemic. Economists such as Larry Summers believe that the prospect for the future is most likely one of secular stagnation.

Worse, because the recovery has been so weak and fragile, there is a widespread belief that another financial crisis may well beckon. In other words, the neoliberal era has delivered the west back into the kind of crisis-ridden world that we last experienced in the 1930s. With this background, it is hardly surprising that a majority in the west now believe their children will be worse off than they were. Second, those who have lost out in the neoliberal era are no longer prepared to acquiesce in their fate – they are increasingly in open revolt. We are witnessing the end of the neoliberal era. It is not dead, but it is in its early death throes, just as the social-democratic era was during the 1970s.

A sure sign of the declining influence of neoliberalism is the rising chorus of intellectual voices raised against it. From the mid-70s through the 80s, the economic debate was increasingly dominated by monetarists and free marketeers. But since the western financial crisis, the centre of gravity of the intellectual debate has shifted profoundly. This is most obvious in the United States, with economists such as Joseph Stiglitz, Paul Krugman, Dani Rodrik and Jeffrey Sachs becoming increasingly influential. Thomas Piketty’s Capital in the Twenty-First Century has been a massive seller. His work and that of Tony Atkinson and Angus Deaton have pushed the question of the inequality to the top of the political agenda. In the UK, Ha-Joon Chang, for long isolated within the economics profession, has gained a following far greater than those who think economics is a branch of mathematics.

Meanwhile, some of those who were previously strong advocates of a neoliberal approach, such as Larry Summers and the Financial Times’s Martin Wolf, have become extremely critical. The wind is in the sails of the critics of neoliberalism; the neoliberals and monetarists are in retreat. In the UK, the media and political worlds are well behind the curve. Few recognise that we are at the end of an era. Old attitudes and assumptions still predominate, whether on the BBC’s Today programme, in the rightwing press or the parliamentary Labour party.

Following Ed Miliband’s resignation as Labour leader, virtually no one foresaw the triumph of Jeremy Corbyn in the subsequent leadership election. The assumption had been more of the same, a Blairite or a halfway house like Miliband, certainly not anyone like Corbyn. But the zeitgeist had changed. The membership, especially the young who had joined the party on an unprecedented scale, wanted a complete break with New Labour. One of the reasons why the left has failed to emerge as the leader of the new mood of working-class disillusionment is that most social democratic parties became, in varying degrees, disciples of neoliberalism and uber-globalisation. The most extreme forms of this phenomenon were New Labour and the Democrats, who in the late 90s and 00s became its advance guard, personified by Tony Blair and Bill Clinton, triangulation and the third way.

But as David Marquand observed in a review for the New Statesman, what is the point of a social democratic party if it doesn’t represent the less fortunate, the underprivileged and the losers? New Labour deserted those who needed them, who historically they were supposed to represent. Is it surprising that large sections have now deserted the party who deserted them? Blair, in his reincarnation as a money-obsessed consultant to a shady bunch of presidents and dictators, is a fitting testament to the demise of New Labour.

The rival contenders – Burnham, Cooper and Kendall – represented continuity. They were swept away by Corbyn, who won nearly 60% of the votes. New Labour was over, as dead as Monty Python’s parrot. Few grasped the meaning of what had happened. A Guardian leader welcomed the surge in membership and then, lo and behold, urged support for Yvette Cooper, the very antithesis of the reason for the enthusiasm. The PLP refused to accept the result and ever since has tried with might and main to remove Corbyn.

Just as the Labour party took far too long to come to terms with the rise of Thatcherism and the birth of a new era at the end of the 70s, now it could not grasp that the Thatcherite paradigm, which they eventually came to embrace in the form of New Labour, had finally run its course. Labour, like everyone else, is obliged to think anew. The membership in their antipathy to New Labour turned to someone who had never accepted the latter, who was the polar opposite in almost every respect of Blair, and embodying an authenticity and decency which Blair patently did not.

Labour may be in intensive care, but the condition of the Conservatives is not a great deal better

Corbyn is not a product of the new times, he is a throwback to the late 70s and early 80s. That is both his strength and also his weakness. He is uncontaminated by the New Labour legacy because he has never accepted it. But nor, it would seem, does he understand the nature of the new era. The danger is that he is possessed of feet of clay in what is a highly fluid and unpredictable political environment, devoid of any certainties of almost any kind, in which Labour finds itself dangerously divided and weakened.

Labour may be in intensive care, but the condition of the Conservatives is not a great deal better. David Cameron was guilty of a huge and irresponsible miscalculation over Brexit. He was forced to resign in the most ignominious of circumstances. The party is hopelessly divided. It has no idea in which direction to move after Brexit. The Brexiters painted an optimistic picture of turning away from the declining European market and embracing the expanding markets of the world, albeit barely mentioning by name which countries it had in mind. It looks as if the new prime minister may have an anachronistic hostility towards China and a willingness to undo the good work of George Osborne. If the government turns its back on China, by far the fastest growing market in the world, where are they going to turn?

Brexit has left the country fragmented and deeply divided, with the very real prospect that Scotland might choose independence. Meanwhile, the Conservatives seem to have little understanding that the neoliberal era is in its death throes.

Dramatic as events have been in the UK, they cannot compare with those in the United States. Almost from nowhere, Donald Trump rose to capture the Republican nomination and confound virtually all the pundits and not least his own party. His message was straightforwardly anti-globalisation. He believes that the interests of the working class have been sacrificed in favour of the big corporations that have been encouraged to invest around the world and thereby deprive American workers of their jobs. Further, he argues that large-scale immigration has weakened the bargaining power of American workers and served to lower their wages.

He proposes that US corporations should be required to invest their cash reserves in the US. He believes that the North American Free Trade Agreement (Nafta) has had the effect of exporting American jobs to Mexico. On similar grounds, he is opposed to the TPP and the TTIP. And he also accuses China of stealing American jobs, threatening to impose a 45% tariff on Chinese imports.

To globalisation Trump counterposes economic nationalism: “Put America first”. His appeal, above all, is to the white working class who, until Trump’s (and Bernie Sander’s) arrival on the political scene, had been ignored and largely unrepresented since the 1980s. Given that their wages have been falling for most of the last 40 years, it is extraordinary how their interests have been neglected by the political class. Increasingly, they have voted Republican, but the Republicans have long been captured by the super-rich and Wall Street, whose interests, as hyper-globalisers, have run directly counter to those of the white working class. With the arrival of Trump they finally found a representative: they won Trump the Republican nomination.

Trump believes that America’s pursuit of great power status has squandered the nation’s resources

The economic nationalist argument has also been vigorously pursued by Bernie Sanders, who ran Hillary Clinton extremely close for the Democratic nomination and would probably have won but for more than 700 so-called super-delegates, who were effectively chosen by the Democratic machine and overwhelmingly supported Clinton. As in the case of the Republicans, the Democrats have long supported a neoliberal, pro-globalisation strategy, notwithstanding the concerns of its trade union base. Both the Republicans and the Democrats now find themselves deeply polarised between the pro- and anti-globalisers, an entirely new development not witnessed since the shift towards neoliberalism under Reagan almost 40 years ago.

Another plank of Trump’s nationalist appeal – “Make America great again” – is his position on foreign policy. He believes that America’s pursuit of great power status has squandered the nation’s resources. He argues that the country’s alliance system is unfair, with America bearing most of the cost and its allies contributing far too little. He points to Japan and South Korea, and Nato’s European members as prime examples.He seeks to rebalance these relationships and, failing that, to exit from them.

As a country in decline, he argues that America can no longer afford to carry this kind of financial burden. Rather than putting the world to rights, he believes the money should be invested at home, pointing to the dilapidated state of America’s infrastructure. Trump’s position represents a major critique of America as the world’s hegemon. His arguments mark a radical break with the neoliberal, hyper-globalisation ideology that has reigned since the early 1980s and with the foreign policy orthodoxy of most of the postwar period. These arguments must be taken seriously. They should not be lightly dismissed just because of their authorship. But Trump is no man of the left. He is a populist of the right. He has launched a racist and xenophobic attack on Muslims and on Mexicans. Trump’s appeal is to a white working class that feels it has been cheated by the big corporations, undermined by Hispanic immigration, and often resentful towards African-Americans who for long too many have viewed as their inferior.

A Trump America would mark a descent into authoritarianism characterised by abuse, scapegoating, discrimination, racism, arbitrariness and violence; America would become a deeply polarised and divided society. His threat to impose 45% tariffs on China, if implemented, would certainly provoke retaliation by the Chinese and herald the beginnings of a new era of protectionism.

Trump may well lose the presidential election just as Sanders failed in his bid for the Democrat nomination. But this does not mean that the forces opposed to hyper-globalisation – unrestricted immigration, TPP and TTIP, the free movement of capital and much else – will have lost the argument and are set to decline. In little more than 12 months, Trump and Sanders have transformed the nature and terms of the argument. Far from being on the wane, the arguments of the critics of hyper-globalisation are steadily gaining ground. Roughly two-thirds of Americans agree that “we should not think so much in international terms but concentrate more on our own national problems”. And, above all else, what will continue to drive opposition to the hyper-globalisers is inequality.
