I (as will shortly become obvious) am no economist, but presuming that some US companies do business with people outside of the USA, if we are taxing those businesses are we not also gaining some tax revenue from people who are not in the USA - i.e. who are not us?
I'm also curious why, if business taxes are so bad and only appeal to the ignorant, just about every country seems to tax businesses. Do we lack non-ignorant people setting tax policy throughout the entire world (give some of the other laws created, I wouldn't doubt it for a minute) or are those setting the policies simply pandering to the ignorant masses that elect them?
