Hey, man. For all the American boasting about "freeeeedumb!!!", let me tell you what it's financially like being an expat outside of the country. It's not just that the US will tax you anywhere you live in the world, even if you earned no income in the US.
But also because of
FACTA, nobody who offers financial services outside of the US can touch me. They literally cannot take my money as a US citizen other than pretty much a zero-interest bank account. Any investments I do have to all go through US accounts.
The US has super tight butthole financial monitoring on Americans all around the world, and they strong arm the rest of the world's financial services orgs to comply with their demands to not touch their citizens. It's like having your finances monitored the way that Russia monitors all the data held on its citizens. We're talking Stasi-level Big Brother.
Free country, my ass. No other country in the world does this.
