What Should Interest Legislators?

In England, budget cuts to food subsidies for students is reported in the Guardian:

A coalition of senior doctors and nurses have written to the education secretary, Michael Gove, expressing "deep concern" at his decision to axe plans for free school meals for half a million primary school children from low-income families.

While in the U.S. research points to the school lunch program as a proven intervention:

The study finds that the program leads to a significant increase in educational opportunity and attainment, but an insignificant increase in health levels from childhood to adulthood.

Other research points toward the "earned income credit" being the most significant education intervention in history. (W. Thomas Boyce U of British Columbia, Vancouver

Are there things the government can and should be doing that will help grant all citizens equal access to early development? Should these things create a foundation of public policy? I think so.
