True, though there need to be controls on this sort of change. That's why we have things like tariffs. If you just open the flood gates on cheap imported labor, you'll decimate the domestic economy and then everyone loses. It's like over-cutting wood for fuel. If you impose restrictions, then forests have time to recover and you have more wood in the long run. If you don't, then forests die out and no one gets any wood. The "wood", in this case, is the money large companies are taking from domestic workers and giving to foreign workers (which they then go and spend in foreign economies i.e. the money is not spent in the economy that supports the large company and said arbitrage bites them in the butt).
