A proposal to satisfy Warren Buffett and raise his taxes

I’m tired of hearing Warren Buffett complain about not paying enough in taxes.

I propose a 10% property tax on all Americans with personal wealth in excess of $40 billion. This should bring the government about $10.5 billion in new revenue; $4.4 billion from Warren Buffett and $6.1 billion from Bill Gates.

What say you Mr. Buffett? Willing to put your money where your mouth is?
