Answer:
option 2 is the answer - Domestic firms can hire low-skilled workers anywhere in the world.
Step-by-step explanation:
The increase in offshore activities and international trade leads to income inequality. When U.S trade with other countries that export goods to America, low-income workers in the sector that originally produced similar goods, face threats from competition.
Some domestic companies (mostly in the manufacturing sector), end up hiring foreign workers, who could do the same jobs as U.S citizens, but with lower wage requirement.
