The company is still using a person’s material situation to pay them less. More purchasing power in their subjective economy is part of their material situation. They are still receiving monetarily less as is their country.
Less than what? Your personal belief that they should be paid a us salary because you say so? And if so, should that be a new York city salary, a Louisiana salary, or?
I directly covered your second point, while they do spend the money they earn from their American job within their economy they are not being paid the exact value of their labor because profit is being extracted so the amount of money they stimulate their economy with is not as valuable as their labor would be. I don’t want to explain the entire labor theory of value here because it would take up too much time and space but you can look into it if you’d like. Put simply, the profit that company makes is extracted from that employees labor meaning that some of their labor is being used not to benefit their country or people but another’s. Outsourcing is an extraction of mans most valuable resource from the less fortunate to the more
Again you have this imaginary number in your mind that you feel everyone should be paid regardless of circumstances. I keep thinking this is not ethical, but from an economic standpoint the Filipino employee is better off than working for less money for a local employer or not working at all because of unemployment. And so are his family and their government.
Stop comparing with the American salary, it doesn’t make any sense. If the American company was paying an American salary, they would hire someone in the states.
