Im also wondering about that figure, not that I doubt it at all, just would be interesting to see the breakdown.
-workers who want more $$$ for relatively repetitive simple assembly line work
-workers who know how to negotiate health insurance
-workers who want over time
-who knows how many people you would need to match the productivity of one shift out of America
-workers in America have an over estimated value of what they're worth financially, which SHOULD be what you negotiate, not some set standard.
I think I read somewhere that was straight out of the Steve Jobs book saying why jobs decided to make them out of the US, if what I read was true I can't blame him.
