Peter Singer has a lovely idea: The Life You Can Save, a plan to reduce poverty worldwide.

I do have one objection. This is basically a plan for wealth redistribution, which I think is a reasonable objective. However, the only people who are going to be helping others are those willing to participate voluntarily — the selfish greedy bastards won’t feel a thing. Shouldn’t there be, like, a policy of progressive taxation that makes the excessively wealthy contribute more to easing poverty? That seems fairer to me.
