A while ago I asked if schools were nothing more than a glorified day care. Matt Yglesias provides an answer:
Two things I've heard a lot about today are the benefits of preschool for the parents of the kids enrolled, and the endless debate over Head Start. These turn out to be linked, however. That's because Head Start turns out to be lousy preschool, but pretty impressive child care.
It turns out, as I had initially suspected, that the answer is yes. It looks like I’m right again.
