>The US is the only country that taxes worldwide income.
Technically no, so does Eritrea tax non-resident citizens on their worldwide income.
And it's frankly hard to make sense of the rest of your comment.
It's difficult (or impossible?) as you say for an American citizen to basically be a perpetual tourist, not actually residing anywhere?
>to pay a crazy US rate instead of the far more reasonable 13% in russia.
>All the comments about scandi countries assume people actually declare income without using many more legal strategies available there compared with the US.
Well, yes, I am assuming that people generally don't try to live as a perpetual tourist and skirt tax burdens by not actually living anywhere.
>The effective tax situation for wealthy US citizens is actually much worse, it is just obfuscated by the headline number.
Still eager to see this proved.
