Gah, it's not even the politicization! I dare you to sit through a 3rd grade class at your neighborhood school. Nothing gets done. They do projects with little to no mooring to curriculum. That is, unless you live in a top percentile district that values curriculum mapping, but then you were already going to be in the middle class at least. In the meantime, most of these schools are day cares so parents can work. Marx wasn't that wrong.
