The $70 an hour claim has actually been debunked as inccurate.

But then what's the source of that $70 hourly figure? It didn't come out of thin air. Analysts came up with it by
including the cost of all employer-provided benefits--namely, health insurance and pensions--and then dividing by the number of workers. The result, they found, was that benefits for Big Three cost about $42 per hour, per employee. Add that to the wages--again, $28 per hour--and you get the $70 figure. Voila.
Except ... notice something weird about this calculation? It's not as if each active worker is getting health benefits and pensions worth $42 per hour. That would come to nearly twice his or her wages. (Talk about gold-plated coverage!) Instead, each active worker is getting benefits equal only to a fraction of that--probably around $10 per hour, according to estimates from the International Motor Vehicle Program.
The number only gets to $70 an hour if you include the cost of benefits for retirees--in other words, the cost of benefits for other people. One of the few people to grasp this was Portfolio.com's Felix Salmon. As he noted friday, the claim that workers are getting $70 an hour in compensation is just "not true."

n essence one only arrives at the $70 an hour by adding all salaries, bonuses, benefits, pensions, etc of all the past living employees (retirees) and dividing it by the number of ACTIVE employees.
The actual wage of a autoworker is $28 an hour which is the same as the Japanese car manufacturers.
