Must be my day for Heinlein quotes:

Stupidity cannot be cured with money, or through education, or by legislation.
Stupidity is not a sin, the victim can't help being stupid. But stupidity is the only
universal capital crime; the sentence is death, there is no appeal and execution
is carried out automatically and without pity.

-- Lazarus Long (Robert Heinlein, "Time Enough for Love")
