It is one of the ironies that billionaires talk about paying higher taxes while at the same time pay scads of accountants to help them find every possible write off to lower the tax burden they pay. Not unlike the Clintons. It wasn't all that long ago that Hillary told a foreign journalist that the "rich" are not paying their fair share, all the while she must know that the facts don't bear that out. The top 2% pay the vast majority of the income taxes in this country already. Many people in this country don't pay anything above payroll taxes that they then get a refund back from.
I would find it much more believable if people like Warren Buffett and Hillary Clinton paid taxes on their income without any write offs. No one is stopping these people from giving money to the treasury. The reason they don't is they know what all conservatives are aware of, the government will just waste it, yet they keep pushing for more and more government programs. Buffett is obviously not a stupid man, but his actions don't back up his statements. Cavuto says it best:
