"David Friedman.  The Machinery of Freedom, 2nd edition (via andrealdn)
When I used to give speeches in favor of abolishing the draft, there was a dirty word that kept cropping up - ‘mercenary’.
A mercenary, as far as I could figure it out, was someone who did something because he wanted to. A soldier who fought for money. Or glory. Or patriotism. Or fun. The opposite of a mercenary was a draftee. Someone who fought because if he did not, he would be put in jail.
According to that definition, there are only two kinds of people. Mercenaries and slaves. I’m a mercenary."
