Economists who work on things like child care don’t generally get the big jobs at Harvard and the Fed. Some of them do it anyway, but they still are required to talk about it only in the purest business-guy dialect. (Can we call it Avarese?) For some reason, “We’re going to wake up one day and find out that unless we take care of our child-care business, we’re not going to have a sustainable, growing economy” gets more attention than, say, “Kids need a safe, fun place to be while their parents are out doing what they have to do.”
