> They're also the kids that are least likely to improve despite any number of things that might happen in the school, including basically unlimited educational funding.
This is not true.
The Gates Foundation, whom I generally dislike quite intensely for being busybody carpetbaggers who muck things up and disappear, documented this all very well. 2 teachers and 15 students per class works. Period. Every single program that did this showed significant improvements with the most improvement in the lowest performers.
The biggest problem, of course, is that when you ask for money for 2 teachers per 15 students everybody loses their minds (except the rich, of course, who understand the correlation perfectly). Every single one of the programs that the Gates Foundation documented as working were eventually shut down because of lack of funding.
People only say they want better education. Their actions say otherwise.
