Globalization is a step in the direction of automation. Robots are expensive; the scale of the operation has to be large to mitigate that. So globalization is a step in the direction of automation - labor is cheaper in India or China.

Witness: factories come back to America, but only once scale increases (or automation gets cheaper) to the point robots are even cheaper than India or China. The returned factories have no labor jobs - its all robots.

So ok, its all the same effect - nobody is going to pay a living wage for labor any more.
