Graphs, etc included on source page. Also noted is some movement to cut down the cost of wages/benefits.
Blue Collar work is simply not worth $76 per hour (wages and benefits) and if that happens other than in the auto industry, more jobs and production of 'everything' will go to foreign countries.
I'll be out $80,000 if GM goes down, but they should go down with the opportunity to draw up a viable business plan and to hire workers at a competitive salary with competitive benefits. Unions are greedy bastards.
