Billionaire investor Warren Buffett said he doesn’t want to be “coddled” by Congress, that wealthier Americans should pay higher taxes and that higher taxes do not dampen job growth. In an opinion piece published today in The New York Times, Buffett said taxes should be raised on Americans who make at least $1 million per year. He said his 2010 federal tax bill, including income and payroll taxes, was $6,938,744. “That sounds like a lot of money,” Buffett said. “But what I paid was only 17.4 percent of my taxable income — and that’s actually a lower percentage than was paid by any of the other 20 people in our office.”
