Yesterday President Obama gave a speech to his union supporters in Detroit. His warm-up act, Jimmy Hoffa Jr., outrageously called for union members to “take the sons of bitches out,” referring to Republicans and/or Tea Party members. Both gave passionate speeches praising the virtues of union labor and collective bargaining. When it was all over I was left with one nagging question.

With whom will you “collectively bargain” when there are finally no employers left?
