It’s called tithing

The church thought of this first, but better late than never, I suppose: 10 over 100 is an effort to encourage people who make over $100,000 per year to donate 10% to charity.

Here’s the pledge: I, [type your name here] , hereby make a personal promise to give 10% of whatever I make over $100,000 each year to charity. I will donate money directly to organizations of MY choosing, including charities, relief funds, schools, churches, etc. I understand that this promise is morally, not legally, binding.

Update: FWIW, under a “graduated tithe” of the type advocated by Ron Sider, with a scale of, say, $10,000, and basic expenses set at $40,000, you would be giving 60% per $10k once you reached $100,000 in income. So at the $100,000 level, you’d be giving a total of $25,000 or 25%. Beyond this, you increase gradually until you would be giving 100% of the money earned past $140,000.
