There are innumerable problems in America’s educational systems. One is that the gap between the higher performing students and the lower performing students in all areas (including humanities, arts, and sciences) is increasing. Another is that educational systems, spurred by taxpayers who don’t want higher taxes, have learned not how to effectively cut expenses but have sacrificed education by packing more students into a classroom; almost every study (including the PISA testing) shows a link between class size and educational achievement.
