Warren Buffet makes two separate arguments in favor of raising taxes on the very rich:

1. Anecdotally the über-rich wouldn't mind paying more and won't invest in US markets in markedly different ways

2. The über-rich aren't paying their fair share of taxes because their tax percentage is much smaller than everyone else.

The first point is a good one, but it's the second point that the Forbes article is criticising - and to my mind rightly so. Why shouldn't you include corporate income tax and sales tax when it comes to calculating a person's tax percentage? I'd love to hear Warren Buffett's response to this criticism.
