I assume you've never been in a foreign country when it fell apart and the US government had to evacuate their citizens. Some other expatriates weren't so lucky.

I have, actually (Kenya). I'm also lucky enough to hold the passport of another developed country that helps its expatriates and doesn't have a regressive expatriate tax system, so I can compare.

I need to add that a country providing expatriate safety services has nothing to do with a tax system and everything to do with supporting the country's imperialist interests.

It's much harder to get your citizens to work in your interest in risky foreign countries if you aren't willing to back them up.

Fun fact: if evacuated in the manner you describe and as a civilian, you get a bill for it.

I really doubt this is a major worry for a tax exile living in Monaco.
