"We don't mind paying taxes at Berkshire... the rate was 35% not that long ago, and it's been 52% in the past, when I've been operating... We don't mind paying taxes at Berkshire, and we are paying a 21% federal rate... ... If we send in a check like we did last year, we sent in over $5 billion to the US federal government. And if 800 other companies had done the same thing, no other person in the United States would have had to pay a dime of federal taxes, whether income taxes, no Social Security taxes, no estate taxes, no… It's open down the line."
