Just what i read it online in forbes i think awhile back. It was actually 30 years and out though. Was from an article from 2009. I got a screen shot it wont let me load. Start at 18, retire at 48. You got to admit though a chapter 7 reorganization of the company would have forced the UAW back to the table, and allowed GM to cut the legacy costs and become lean and mean. Other than that I will keep it back on topic.
