Warren Buffett agrees: Tax the rich

We reported Friday on a group of millionaires calling for their tax breaks to expire. Now, Warren Buffett -- the third richest man in the world -- is joining that chorus.

Buffett told ABC News' Christiane Amanpour that tax breaks for the rich don't help the economy.

"The rich are always going to say that, you know, just give us more money and we'll go out and spend more and then it will all trickle down to the rest of you," Buffett said. "But that has not worked the last 10 years, and I hope the American public is catching on."

The complete Buffett interview will air during a Thanksgiving edition of "This Week," but you can watch an excerpt below:
