In education, it is said that the state must impose schooling on all children, else the parents and communities will neglect it. Only the state can make sure that no child is left behind. The only question is the means: will we use the union and bureaucracies favored by the left, or the market incentives and vouchers favored by the right. I don't want to get into a debate about which means is better, but only to draw attention to the reality that these are both forms of planning that compromise the freedom of families to manage their own affairs.
