It's kind of funny to hear wealthy individuals complaining about not taxing their class proportionally. As if they are saying "This is wrong. But unless the government tells us we have to pay, we're still not going to pay."

Why don't these individuals, e.g. Buffett, this TED speaker, and others, just lead by example. Overpay their taxes to amount to whatever they think is fair.

Why do they have to wait for the government to tell them they must pay?

Or they say they will pay more only if other wealthy individuals do the same.

Either they believe in paying a bigger share or they don't.

This "I'm not going to do it unless he does too" attitude is child-like behaviour.
