There is one thing, however, which I don't know how we can fix, at least not from a legislative or policy standpoint, and that is the lack of parental participation.
While I agree with some of your points, I'll take issue with this statement. In my opinion, the lack of parental participation and school/legislative policy have degenerated in a vicious cycle. Schools try to do more to help kids, while discouraging/preventing parental influence on school policy. As a result, parents are less involved, which leads the school to do more, etc.
As for "day long day care" - so true. Look no further than the push for 4k and Head Start, which have repeatedly and consistently failed to produce lasting benefits, while costing taxpayers *billions*. There's no educational justification for it.
