     If the '60s were over in 1972, the ’70s were in trouble by 1977. Don't get me wrong — the Eagles and Foreigner and Earth, Wind & Fire are, er, survivors. Good or bad they're careerists, they jog two miles a day, and they're all destined to outlast the Ramones.

     Heckman has been analyzing data from two famous early-childhood intervention programs, the Abecedarian Project of the ’70s and the Perry Preschool project of the ’60s. Both have furnished ample evidence that, if you enroll very young children from poor families in programs that give both them and their parents an extra boost, then they grow up to be wealthier and healthier than their counterparts—less fat, less sick, better educated, and, for men, more likely to hold down a job.
