What moral attitude should we take toward Globalism?

From the American workers view the positive side of Globalism is that many workers worldwide in very poor countries will experience a significant increase in their standard of living because the manufacturing of certain products that were manufactured in America are manufactured in their country.

From the American workers view the negative side of Globalism is that the standard of living of many Americans will decline significantly because of the work that has gone to poor countries.

From the American capital owning and financial brokerage view Globalism is the best thing since sliced bread.

What moral judgment should all Americans take toward Globalism? I have no answers to this very difficult question. This is the type of question that leads some people, like me, to duck their moral principles.

I suspect that Americans with capital will reap great advantage from Globalism but working Americans will be net losers. The workers and the capital owning citizens in poor countries will be large net winners.
