Have Unions outlived their goals?

[Momforlife]

I applaud the Wisconsin Democrats that went MIA, to avoid a vote that they were not ready to vote on. The Republican Governor decides one day to cancel all collective bargaining with the State Unions? I am not a big Union defender, but this is a slippery slope if we allow this to happen.
Democrats country wide need to get some balls and do exactly what these guys are doing! Obama included!
