There's a long-held debate in education. " 'Do you fix education to cure poverty or do you cure poverty to cure education?' And I think that's a false dichotomy," says the superintendent of Camden schools in New Jersey, Paymon Rouhanifard. "You have to address both."

That can be expensive.

One result: Camden City School District spends $35 million a year on preschool. That buys two teachers for every 15 students and quality coaches for those teachers.
