Bingo. Government run schools enforce the idea of subservience to "superiors" and dependence on government. Add in a good dollop of marxism with its group-think and you create a generation who can't think on their own, are afraid to strike out in new directions, and who are always seeking approval from the "group".
Correct and it isn’t just at government run schools. Government sets the curriculum standards by law and by purchasing power. It’s hard to get around the behemoth’s reach.
