No, it matters in the extreme. He's opening his mouth and calling for taxes on The Rich. Why? Because of our massive deficit and even more massive debt issues. So, that's fine. As a rich person, has he done what he's advocating, given there's already a means for him to do so, for the problem he sees that he wants taken care of?
No.
He should be making sure he's giving his 35%, then donating. When he's done that, let us know. Until then he's all talk.

To borrow a quote from The West Wing, "What's next, imaginary street signs?"
Even if you believed that everyone is morally obligated to act as if the laws they propose are already in effect, whether Buffetf is "all talk" has very little to do with whether his point is valid or not. The fact that's he's not voluntarily pretending his proposed idea exists makes his argument more credible since it would result in an actual change in his after-tax income (not the case if he paid imaginary taxes).
Warren Buffett's argument has never been that he personally needs to pay higher taxes so much as he's arguing that EVERYONE who makes several times the national average should have higher effective tax rates. Leading by example doesn't seem particularly relevant here.
