Don Boudreaux over at Cafe Hayek nails it:
While Kennedy didn’t choose a life of ease, he did something much worse: he chose a life of power. That choice satisfied an appetite that is far grosser, baser, and more anti-social than are any of the more private appetites that many rich people often choose to satisfy.
A true altruist gives his money or time to others, via friendship or charity. They don't write laws that force me to serve their ends.
