Oh my God! Come on guys, Marx is saying that all children, no matter who they are or where they come from, should be given access to education that is given adequate funding by the state, so that no child will be denied the right to go to university or school because they can't afford it, or because the children of those who can afford it will do better, purely because they had more money thrown at them. At the moment state education is failing, but that is because our governments prefer to spend money on the military or on tax breaks for the rich. The ideal it is based on: that everyone should have the right and actively be encouraged and assisted in every way to be educated, is not being met by governments but it is how society should be run. Marx doesn't want to deny any parent the right to educate their children. The phrasing of the quote only reflects Marx's phraseology, as he was writing in the 19th century; none of his books ever said anything about taking away parental rights, but only improving the family through the security of a free and high standard of education for all. Go Marx!
