The Almighty
The current business model was working for about 30 years for Ford, GM (sell big trucks at a huge profit and sell cars at a loss). Just because it's working now doesn't mean it will continue to work. If GM, Ford, and Chrysler all make a come back and are stealing market share, all while their employees are getting paid well. Well, expect Toyota and Honda to lose some of their best workers.
True, if the big three change their business models to something successful (yes, I am laughing hard at that, unless current management is replaced) but IF they do... AND Toyota etc.. do nothing to change, then you are correct. BUT none of that says they have to unionize to make changes or to offer competitive salaries.
Again, the employees have the option of forming a union if they feel they are being unfairly compensated.
