Of course, it was inevitable. As soon as Warren Buffett came out and publically said that the super-rich, like himself, should be taxed more, knee-jerk, reactionary right wingers were going to throw the “S” word at him.
It is a laughable notion - one of the most successful traders in history wants to march America towards communism. His critics seem to be completely thrown by the fact that Buffett, gasp, has a conscience.
Right-wing political correctness has taken the word socialist and turned it as a club to beat anyone who believes in progressive taxation, public goods or any regulation of externalities.
