An Open Letter to the US President: Why are you Stealing my Money‪?‬

I am an erotica author.Every month when I am paid for my global sales by US companies I have withholding tax taken out by US tax authorities.
But much of the tax they are taking from me is really for sales that I, a non US citizen, have made to readers in Australia, or Sweden or one of another hundred countries.
I am sick of US government stealing my money, thus my open letter to the US President!
