Americans are much more likely than citizens of other nations to believe that they live in a meritocracy, i.e. Government by people selected according to merit. But this self-image is a fantasy: America actually stands out as a the advanced country in which it matters most who your parents were, the country in which those born on one of society’s lower rungs have the least chance of climbing to the top or even to the middle.And if you ask why America is more class-bound in practice than the rest of the Western world, a large part of the reason is that our government falls down on the job of creating equal opportunity.The failure starts early: in America, the holes in the social safety net mean that both low-income mothers and their children are all too likely to suffer from poor nutrition and receive inadequate health care. It continues once children reach school age, where they encounter a system in which the affluent send their kids to good, well-financed public schools or, if they choose, to private schools, while less-advantaged children get a far worse education.
