Charles Murray, who wrote The Bell Curve, has a new book out called
Losing Ground: American Social Policy, 1950-1980. The Time magazine article I read is online for subscribers only (I read it in a waiting room), but it was basically that all of the classes are isolating themselves and don't really cross-pollinate much, so the rich get richer and the poor get poorer, and kids whose parents make bad decisions only hang out with other kids whose parents make bad decisions, so there's never any way for them to learn how to make better decisions.
Per wikipedia, the book ultimately calls for the end of all social programs.

The book:
