A team of NYT reporters has been working for a year on series about the role of social class in contemporary America.

Here's some excerpts from part one:

The trends are broad and seemingly contradictory: the blurring of the landscape of class and the simultaneous hardening of certain class lines; the rise in standards of living while most people remain moored in their relative places.

Even as mobility seems to have stagnated, the ranks of the elite are opening. Today, anyone may have a shot at becoming a United States Supreme Court justice or a C.E.O., and there are more and more self-made billionaires. Only 37 members of last year's Forbes 400, a list of the richest Americans, inherited their wealth, down from almost 200 in the mid-1980's.

So it appears that while it is easier for a few high achievers to scale the summits of wealth, for many others it has become harder to move up from one economic class to another. Americans are arguably more likely than they were 30 years ago to end up in the class into which they were born.

A paradox lies at the heart of this new American meritocracy. Merit has replaced the old system of inherited privilege, in which parents to the manner born handed down the manor to their children. But merit, it turns out, is at least partly class-based. Parents with money, education and connections cultivate in their children the habits that the meritocracy rewards. When their children then succeed, their success is seen as earned.

The scramble to scoop up a house in the best school district, channel a child into the right preschool program or land the best medical specialist are all part of a quiet contest among social groups that the affluent and educated are winning in a rout.

"The old system of hereditary barriers and clubby barriers has pretty much vanished," said Eric Wanner, president of the Russell Sage Foundation, a social science research group in New York City that recently published a series of studies on the social effects of economic inequality.

In place of the old system, Dr. Wanner said, have arisen "new ways of transmitting advantage that are beginning to assert themselves." ...

Is there such a thing as a 'class'?

A few sociologists go so far as to say that social complexity has made the concept of class meaningless. Conventional big classes have become so diverse - in income, lifestyle, political views - that they have ceased to be classes at all, said Paul W. Kingston, a professor of sociology at the University of Virginia. To him, American society is a "ladder with lots and lots of rungs."

"There is not one decisive break saying that the people below this all have this common experience," Professor Kingston said. "Each step is equal-sized. Sure, for the people higher up this ladder, their kids are more apt to get more education, better health insurance. But that doesn't mean there are classes."

Many other researchers disagree. "Class awareness and the class language is receding at the very moment that class has reorganized American society," said Michael Hout, a professor of sociology at the University of California, Berkeley. "I find these 'end of class' discussions naïve and ironic, because we are at a time of booming inequality and this massive reorganization of where we live and how we feel, even in the dynamics of our politics. Yet people say, 'Well, the era of class is over.' "

Better opportunities in Canada?

One surprising finding about mobility is that it is not higher in the United States than in Britain or France. It is lower here than in Canada and some Scandinavian countries but not as low as in developing countries like Brazil, where escape from poverty is so difficult that the lower class is all but frozen in place.

Those comparisons may seem hard to believe. Britain and France had hereditary nobilities; Britain still has a queen. The founding document of the United States proclaims all men to be created equal. The American economy has also grown more quickly than Europe's in recent decades, leaving an impression of boundless opportunity.

But the United States differs from Europe in ways that can gum up the mobility machine. Because income inequality is greater here, there is a wider disparity between what rich and poor parents can invest in their children. Perhaps as a result, a child's economic background is a better predictor of school performance in the United States than in Denmark, the Netherlands or France, one recent study found.

"Being born in the elite in the U.S. gives you a constellation of privileges that very few people in the world have ever experienced," Professor Levine said. "Being born poor in the U.S. gives you disadvantages unlike anything in Western Europe and Japan and Canada." ...

Clearly, a degree from a four-year college makes even more difference than it once did. More people are getting those degrees than did a generation ago, but class still plays a big role in determining who does or does not. At 250 of the most selective colleges in the country, the proportion of students from upper-income families has grown, not shrunk.

I'm really looking forward to the rest of this series!
