Last week offered a chance to collectively gawp at the super-wealthy. Mexico's Carlos Slim and the US's Bill Gates were in a run-off to be the world's richest billionaire in the Forbes list of the 1,011 people with personal wealth in excess of a billion dollars. In the event Slim's $53.5bn just pipped Gates' $53bn. It was a moment of symbolism, opined the global commentariat. The economic baton was passing from the US to countries in Asia and Latin America. And we all could relax; the numbers of billionaires was growing again – proof positive that the global economic machine was picking up.

It is the ultimate degeneracy of the age. There is little critical appraisal of billionairedom. It is just accepted that loadsamoney, capitalism, jobs and economic progress are indissolubly linked. More billionaires of any hue is a sign of economic vitality. Lucky Mexico for coming up with the winner. But wealth is not connected to economic progress in a linear way. Wealth can come from productive or unproductive entrepreneurship. Society wants the former and deplores the latter. If you want to be seriously wealthy the message from the Forbes list is clear. One way or another you need to have played the system, played the financial markets, been born to the right class or manipulated government to have got rich. This is a list of expropriated wealth on a Midas-like scale. Marx will be grimly smiling in his grave.

Too few of the world's billionaires can claim to be honest-to-God productive entrepreneurs who have enlarged the economic pie by dint of hard work, imagination, risk taking and innovation – although thankfully a useful proportion do populate the list. But a depressingly large number constitute a ragbag of monopolists, oligarchs gifted assets and profits by the state, mega-financial engineers or just family plutocrats. And once on the list you tend to stay there; there is little churn. The arteries of capitalism are hardening.

Sixty-two of the 1,011 are Russian oligarchs. Twenty eight are Turkish oligarchs. Even Carlos Slim made his fortune from being the monopolist who controls 90% of Mexico's telephone landlines and 80% of its mobile phone subscribers. The OECD notes that he charges among the highest usage fees in the world. But hey! He is a billionaire and what matters today are his riches – not the manner in which the money is made. He may have started out as a productive entrepreneur. Today he is using his power to expropriate wealth on a mega scale.

The contrast with his rival Bill Gates could hardly be greater. Microsoft may have had its head-to-head confrontation with the EU Commission over anti-competitive practices, but Gates built his company by innovating around one of the great historic general purpose technologies. Information and communication technology is like the railway, internal combustion engine or air travel – a technology with massive spill-overs and implications for society. It is a classic example of productive entrepreneurship. Gates may not deserve $53bn, he was lucky to be in the right place at the right time with a great university system around him, but he undoubtedly deserves to be rich. Both Gates and Slim are exploiting their market position to get above average profits, but one is more overtly political than the other. Put another way, Gates has grown the economic pie. Slim represents a tax on it.

The good news for the US is that even if its share of global billionaires has fallen to 40%, a disproportionately high share are still productive entrepreneurs. There are figures on the list – like the Walton family riding high on Walmart – who have inherited their money, but most have made their fortunes from socially and economically useful activity and whose profits and market position are being actively challenged in the market place. A large proportion of the Indian entrepreneurs are in a similar position, although the relationship with the Indian state is sometimes more murky. Mukesh Ambani, complete with his 70-storey home in Mumbai, may be extravagantly wealthy at number 4 in the list, but like the number 5, Lakshmi Mittal (who has British residence) he has spawned an industrial empire that is generating jobs and wealth. The productive entrepreneurship spells long-term good news for the US and India – less so for the countries whose billionaires are politicised oligarchs and monopolists.

But strangely not even Forbes magazine makes much of an effort to distinguish how the billions are made. The great truth of capitalism is that it took off only once the European Enlightenment created the great institutions that kept it honest – the rule of law, a free press, accountability mechanisms, ways of forcing monopolists to give up their ill-gotten gains, creating competitive markets and elections. Before that there was tax-farming and the buying and selling of monopolies – rather as in China today. The Enlightenment offered the means, however imperfect, to challenge all that. The great mistake of the free-market revolution was to argue that all that was needed to make capitalism work was free, lightly regulated and flexible markets – and that institutions imposing ethics, transparency, accountability got in the way. We now know better.

Britain's representation in the Forbes list is particularly depressing. Our members include a bunch of property developers, tax-avoiding retail magnates, the Duke of Westminster, a hedge fund manager and Richard Branson. Branson is probably the closest we have to a billionaire productive entrepreneur, but his companies are hardly at the forefront of technological innovation or employment generation. He glamorises – but does little to grow the economy. We do not have one genuinely productive entrepreneur on the list.

In many respects this forms the heart of the British crisis. Our political class bought the proposition that whatever the source of wealth economic progress would follow, celebrating the Mayfair hedge fund manager more than the genuine innovator. Watch the British government now fight on behalf of hedge funds against EU regulation. Only at the eleventh hour, with some of Lord Mandelson's speeches and initiatives, together with David Cameron commissioning a useful report from the entrepreneur James Dyson, Ingenious Britain, is there any sign of change. But it is a deathbed conversion. The electorate, angry and bewildered, want a conversation about creating wealth and jobs, rewarding those that do rather than those that speculate and rig markets. Instead they are offered platitudes and bromides.
