As I recall, Head Start was supposed to help close the gap between the affluent and the poor on the early childhood factors you mentioned: reading materials, reading to the child, and teaching the child to read. I read somewhere that the program was successful in closing that learning gap in the early years, but that it did not significantly change long term outcomes in academic achievement. Is this true, and, if so, why?

Academic achievement is synonymous with an "acculturized sense of entitlement"?
