There is an invisible hand in politics that operates in the opposite direction to the invisible hand in the market. - Milton Friedman

Every friend of freedom... must be as revolted as I am by the prospect of turning the United States into an armed camp, by the vision of jails filled with casual drug users and of an army of enforcers empowered to invade the liberty of citizens on slight evidence.

In which of these respects the public is more stubborn is an empirical question to be judged from the factual evidence, not something that can be determined by reason alone.

The hardest thing in the world to understand is that people operating separately, through their joint relations with one another, through market transactions, can achieve a greater degree of efficiency and of output than can a single central planner.
