Great suggestion by Hilzoy:
I’d like to suggest one further measure aimed at the kids: universal school breakfasts. (Why universal? It saves paperwork, removes stigma, and makes the program much easier to administer.) Besides protecting kids from hunger, school breakfasts also make them more likely to learn and less likely to have behavioral problems. They seem to increase school attendance. We spend lots of time and energy trying to figure out ways to improve our schools; if what we’re interested in is kids actually learning, making sure that they have eaten recently is a pretty good way to start.
