The solution is obvious from where I, a happily childless person, is sitting: The federal government takes over the school system from the states and makes every school a boarding school. Ban private schools. No children are all in a controlled environment with the same access to after-hours resources as all their peers. They do not have to deal with whatever home life fate dealt them and can focus on their education. They will all have access to the same nutritional standards. They will have access to counseling. They will have shelter. Move them around the country randomly every year or two to minimize local influences. Of course, aside from parents not being particularly happy with the idea of not seeing their kids all year, the biggest problem with this is that it is far too meritocratic and equal for most of the wealthy to stomach, and they'd be the ones largely paying for it.
