Buffett said today at Fortune's Most Powerful Women Summit in Washington that the nation's tax code "has gotten distorted to a huge extent," by levying higher taxes on secretaries and janitors than on CEOs and private equity whiners. "We are not taking in enough money at the federal government level," he said. He said tax collections will have to rise back into the 18-20% range from below 15% lately. But Buffett also added a new twist in an interview after his appearance with CNNMoney.com's Poppy Harlow: He said it's time to cut taxes on those outside the top tax brackets. "We're going to need to get more money," said Buffett. "Why not get it from me instead of the guys who will serve us lunch?" [Fortune]
