What is Wrong with Busting Unions?

Perhaps there is something I am missing? What value do Unions provide? Collective bargaining? Let's see...workers as a large group go to a business owner and demand a raise, better health care, a pension, or else! Collective bargaining ends up equalizing workers so those that do a better job don't get rewarded and those that are sub-par can't be fired. A business owner is not bargaining in an actual sense, they are being extorted! I wonder what would happen if businesses got together and collectively bargained with consumers on what prices consumers need to pay them for their services? Oops, that would be collusion and that is illegal. Doesn't it seem when you take something and thrust it into a different, but comparable scenario, and it doesn't pass the sniff test, perhaps it is something we should not be doing? The Unions do just this all while taking a chunk of members paycheck to support politicians that give the unions even more power over the lives of non-union workers. This is exactly why Wisconsin is in turmoil. Unions have the mentality, if you are with us you prosper, if you're not, you suffer. The other promise Unions claim is job security. I have worked for 3 union shops and 1 non-union shop in the past 15 years. Guess which one is still manufacturing in the USA and providing a livable wage for its employees? Now you know why I ask the question. If people can not freely associate then it is oppression. Try working for a school district and NOT join the union.
