If somebody can offer a service at a cheaper more efficient price, why not? All this humbug about salaries that one "deserves" to get is purely protectionist and doesn't benefit anybody. Offering cheaper overall inputs provide better value for all Americans to enjoy. If you're peddling global free trade, you've got to be willing to accept that labour needs to move freely and capitalism dictates that the person who can do it cheaper and offers an apple to apple comparison of quality will win. It's pure economics. If somebody can do something cheaper than you can, and is willing to do it, then there is nothing wrong with it.
