In those industries where the cost of labor is the primary difference in the cost of producing a good and getting it to market, production will shift to the producer who has lower labor cost. This shift is accelerated in a world where barriers to trade are coming down. If all other factors remain constant, this will lead to a decrease in revenue to businesses that pay relatively higher wages to comparable workers, resulting in a contraction of those businesses and more unemployment.
The benefit of this to consumers, assuming all other factors (personal income, for example) remain constant, is a higher standard of living as the cost of goods fall.
