Yeah... look how well that works for the US auto industry. Hey, maybe we could fail too & get a bailout!
Also, banks and insurance companies got far larger loans than the US auto industry: http://en.wikipedia.org/wiki/Troubled_Asset_Relief_Program#P...
The unions wanted to keep the auto workers employed and that's kind of hard to do when the companies go to shit (mainly because of management). It may sound anti-free-market to you, but then you have to consider the bansk got larger loans. How is that a free market? Why not just let them all fail?
So yeah, I would say the union works pretty well for auto industry workers. Unions never sit well with management because their business is to cut costs and maximize profit, employee welfare be damned.
