>In other words: I believe in higher income taxes on people like me, but I’m highly organized to avoid having income to report, and I don’t really believe in taxes because I think I should decide how these surplus resources are spent.
I really don't like this slant. If somebody truly believes in taxes, they would pay taxes they don't need to pay? Nonsense. It assumes so much and paints charitable contributions as... malicious? Or at least it implicitly assumes that Buffett's billions aren't deserved (in whatever sense the author thinks it means to deserve something), and should be assumed to be the property of the public.
Buffett's signed the Giving Pledge, and has given tremendous billions to charity, with many more billions to come. The charitable causes he supports aim to solve real problems that governments are often poorly suited to solve. Having a policy preference of a higher tax rate while minimizing the taxes you pay is not hypocrisy for either billionaires or middle class Joes.
Seems to me that throwing Buffett under the bus is equivalent to saying... "we don't care if you try to help the world. If you're a billionaire, you're evil." If that sort of opinion becomes popular, good luck getting billionaires to give to charity when they're just gonna get yelled at for it.
