No, I do not work for a US company, and the 'nationality' of a company would seem of little relevance here. American workers at Honda plants in the US benefit indirectly from infrastructure and government decisions in Japan; should these US workers be required to pay Japanese taxes?
Are you in a country that could be hostile to the US? Then if you have problems, I believe the US would bail you out.
US embassies are not known for their usefulness to Americans overseas (and are more likely to be targets than refuges in time of trouble), and actions taken by the US government and local responses thereto pose the greatest single danger to expatriate Americans as a whole. Far from having to pay 'protection money' to the US government, we should be receiving compensation for the trouble the US government causes us.
You might not drive on the roads all the time, but where do you drive when you visit the US?
I don't visit the US. Are you suggesting, however, that all visitors to the US be forced to file and pay income taxes to drive on the roads?
US citizens are taxed on their worldwide income, regardless of source, for the sole reason that the US government considers its citizens chattel slaves to be exploited at its discretion.
Let's say that I make money in Singapore and then invest it in the Hong Kong stock market. As long as I don't bring any of my capital gains back to Singapore, Singapore assesses no taxes on those gains, and since I am not resident in Hong Kong, taxes would not be withheld there either. Explain to me, then, why the US government believes it is entitled to a hefty share of my profits though it does not share in the risk, does not put up any of its own capital, and does not offer any services or protection whatsoever related to my investment. In addition, if an American living in, say, France were to trade in the US stock market, he would have to pay taxes on all his gains, whereas his French neighbor could make the very same trades on the very same markets and not pay any US tax (and no French tax as long as he doesn't repatriate the money).
You should also know that US citizens who give up their American citizenship may, at the discretion of the IRS, have their US-based assets taxed for up to ten years thereafter as if they were still citizens. And some dare to call Americans a free people?
