Your logic is incorrect, you are thinking that a "international" folk buying a TV is what they mean. But that's not correct. Paying income taxes, paying tax on cars, paying tax on gas, paying rent, these matter a lot more to the government then you buying an iphone from the apple store in the mall versus one in "international country".

Sure. Any other body hired in their place would still pay taxes PLUS more likely spend more money locally thus boosting local economy.
