Maybe only a really, really rich guy can credibly make the case for why the wealthy should be asked to pay more in taxes. You can’t accuse a big capitalist of “class warfare.” That’s why the right wing despises Warren Buffett and is trying so hard to shut him up. Militant conservatives are effective because they are absolutely shameless. Many of the same people who think the rich should be free to spend unlimited sums influencing our politics without having to disclose anything are now asking Buffett to make his tax returns public. I guess if you’re indifferent to consistency, you have a lot of freedom of action.
