Mark McKinnon: Do We Still Need Unions? No. - Newsweek: "The manufactured Madison, Wis., mob is not the movement the White House was hoping for. Both may find themselves at the wrong end of the populist pitchfork. While I generally defend collective bargaining and private-sector unions (lots of airline pilots in my family), it is the abuse by public unions and their bosses that pushes centrists like me to the GOP. It is the right and duty of citizens to petition their government. The Tea Party and Republicans seek to limit government growth to protect their pocketbooks. Public-union bosses want to increase the cost of government to protect their racket."
