For starters, we’ve added more checks and balances to make decision-making even more difficult — such as senatorial holds now being used to block any appointments by the executive branch or the Senate filibuster rule, effectively requiring a 60-vote majority to pass any major piece of legislation, rather than 51 votes. Also, our political divisions have become more venomous than ever. As Russ Feingold, the former Democratic senator, once remarked to me: At the rate that polarization is proceeding, partisans will soon be demanding that consumer products reflect their politics: “We’re going to have Republican and Democrat toothpaste.”

In addition, the Internet, the blogosphere and C-Span’s coverage of the workings of the House and Senate have made every lawmaker more transparent — making back-room deals by lawmakers less possible and public posturing the 24/7 norm. And, finally, the huge expansion of the federal government, and the increasing importance of money in politics, have hugely expanded the number of special-interest lobbies and their ability to influence and clog decision-making.

Indeed, America today increasingly looks like the society that the political scientist Mancur Olson wrote about in his 1982 classic “The Rise and Decline of Nations.” He warned that when a country amasses too many highly focused special-interest lobbies — which have an inherent advantage over the broad majority, which is fixated on the well-being of the country as a whole — they can, like a multilimbed octopus, choke the life out of a political system, unless the majority truly mobilizes against them.

To put it another way, says Fukuyama, America’s collection of minority special-interest groups is now bigger, more mobilized and richer than ever, while all the mechanisms to enforce the will of the majority are weaker than ever. The effect of this is either legislative paralysis or suboptimal, Rube Goldberg-esque, patched-together-compromises, often made in response to crises with no due diligence. That is our vetocracy.

The Financial Times columnist Ed Luce, the author of the new book “Time to Start Thinking: America in the Age of Descent,” notes that if you believe the fantasy that America’s economic success derives from having had a government that stayed out of the way, then gridlock and vetocracy are just fine with you. But if you have a proper understanding of American history — so you know that government played a vital role in generating growth by maintaining the rule of law, promulgating regulations that incentivize risk-taking and prevent recklessness, educating the work force, building infrastructure and funding scientific research — then a vetocracy becomes a very dangerous thing.
