C.S. Lewis tells you

"Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their consciences." — C.S. Lewis

I should note that when Lewis says "robber barons," he means the roaming government criminals of the pre-middle ages, not (as the Marxists would have it) the businessmen of the 19th century. (Thanks to Jesse Nelson) via LRC Blog
