Please do explain then how literally every single other country in the world with a strong safety net and welfare system has managed to fund it without having to tax expats.
If you want all the benefits and none of the costs of being American…
Because again, in literally every single country except one African dictatorship, they interpret "the benefits" as things that you enjoy while actually being in the country, and therefore something you pay for while residing there. The ability to be a citizen of your native country is an assumed right everywhere else.
The only benefit I'd be enjoying is the right to return to my home country if I ever needed to. You don't have to pay for that in practically any other country. And so, yes, I would have to seriously think about renouncing my citizenship since I'd be paying for essentially nothing. I think that's rather unfortunate.
