I want people to take thought about their condition and to recognize that the maintenance of a free society is a very difficult and complicated thing and it requires a self-denying ordinance of the most extreme kind. It requires a willingness to put up with temporary evils on the basis of the subtle and sophisticated understanding that if you step in to do something about them you not only may make them worse, you will spread your tentacles and get bad results elsewhere.

-- Milton Friedman
