I think there is plenty of blame to go around at GM, Ford, etc. Americans had a lot of disposable income to spend on cars, so management, union leadership and workers were all happy to feed at the trough. While I think workers need some sort of collective bargaining power, it is disheartening to see how quickly powerful unions can become as bad as management.
I still blame management more than the unions. My father-in-law retired as a VP of CONOCO many years ago and we've discussed this several times. He worked in the coal side and came up with Consol (Consolidated Coal, which got bought out back then by CONOCO which then got bought out by Dupont - all of which is now ancient history from the early 1980s). Anyway, he pointed out that the coal companies bargained hard but he felt fairly with coal unions and the unions got good contracts but reasonable ones as well. In his opinion, the automotive companies just rolled over and gave the unions whatever they demanded and never said no. So I laugh when I see people trying to play the pity card for GM and Ford management. It doesn't wash. They could have stood fast against unreasonable demands but instead they gave into them so they wouldn't have to confront the unions and force the unions to really think about what was good for themselves and the company for whom they worked. And the net result is the pension/medical care mess we see today that is eating away at GM and Ford. GM's management took the easy way out in the 1960s and 1970s and figured someone else could deal with the subsequent problems. Well, those birds have come home to roost. And they are still management's birds.
You're right.  Management did roll.  I acknowledged their complicitness.  But for PEOPLE, forget that it's a union, to think they should get paid to not work is  not logical.  Why?  Why should I pay you because you aren't working?  When it comes to Auto, I do blame both sides but you can't logically argue that because I'm on the payroll I should get paid NO MATTER WHAT.  Do people think out the long term impact of that?  Take some personal responsibility or accoutability or whatever you want to call it.  As an able adult you should take care of your own problems rather than making someone else resposible for it.  I just laugh at it.  Matter of fact, I try and just laugh at the irony of everything happening around me.

Because that was the deal that was made. If you pay me to do nothing and you agree to it, who is the bigger fool, you or me?  

Let's turn this argument around. I am an executive. I get paid an immense amount. Company performance in fact diminishes. I demand and receive a substantial bonus. The company's future gets even dimmer. I demand, and receive once again, a golden parachute. The company folds. I go on to a similar job but before I do so I was able to pocket millions in stock options before the company tanked.

Tell me what the moral difference is between this and the above.

See above comments.  I don't agree with either demand and never claimed to so you are preaching to the choir.  Oh and I agreed that when promises are made, they should be kept, please see above posts.  However both income arrangements need to stop.
