Of course each citizen should try to educate him or herself, but only after receiving some essential, basic blocks of knowledge. Formal education should always be free; from kindergarten to PhD. It is free in many European countries, and in several Latin American ones (including Cuba, Mexico and Argentina). China is returning to free education, as it is returning to universal health care. In countries like Chile, people are on the streets right now fighting for free education, and they are winning!
