You: “A bill for what? How do they know what to bill you for if you don’t tell them where and how you made and spent your money?”
Me: Here is a link to show you how other countries do it.
You: “I just said I don’t know how they do it so I can’t comment on it. I can only comment on the American tax system as an American taxpayer.”
If that is not implying that it can’t be done in the U.S., what did you mean? You apparently didn’t even bother to look at the link to find out how it could be done.
