So are you recommending that a foreign company should only pay taxes on what they earn in the US, but a US company should pay taxes on everything it earns everywhere? (i.e. the US government should get 36% of the profits even if something is built/sold in another country, just because the company has its headquarters in the US?) You do realize this would put US corporations at a huge disadvantage to corporations in any other country, right? You can imagine some of the unintended consequences.

I think only Eritrea and the US taxes corporations when brining back money into the country. For obvious reasons other countries realized this was not a good approach and don't do that.
