You have no idea what you're talking about. It isn't just about taxation it's about countries being forced to report to the IRS. If you have a foreign account with a balance over $10k and you fail to report the account (in a filing separate from your tax returns,) you are fined $10k -- no exceptions. If the balance just goes above $10k for even one minute, you are on the hook for reporting that account for as long as you have the account. Except for Eritrea, no other country has citizenship based taxation. Additionally, you can't even open bank accounts overseas as an American with many banks. You also don't seem to understand citizenship law. There are millions of Americans who have never even been to the US, yet must file taxes and report bank accounts. As far as that blue passport getting you on a C130.. That doesn't happen anymore. The State Department routinely leaves Americans stranded in war zones while the French actually send the military to get their people out. US consular services abroad are a joke. I've lived overseas for about 8 of the past ten years and I routinely deal with consular nonsense. Finally, to your point about being 'rich enough' to pay taxes; the exception is only about $96k -- however if your working in Paris or London or Tokyo, that is barely a survival wage for a family. That aside, you still are subject to double taxation as well if you're in a country without a tax treaty. Frankly, I suspect you've never lived as an expat nor do you understand the facets of the law that make it so onerous.
I've worn te uniform of the US military and paid my 'dues,' yet to imply that an overseas American is any less American is offensive. When I am outside the US, I do not consume a single taxpayer funded service. All consular services for the most part are self-funded. If the time comes when I need the Marines to come bail me out, send me the bill and I'll pay cash; otherwise the IRS can leave me the hell alone. I am a proud American, but I despise the Democrats who passed FATCA along with the class warfare rhetoric that led to it. To Democrats, overseas Americans are presumed to be money launderers, drug dealers or tax evader. I am neither yet the burden of proof is on me. Did you know when Insend money to the US, I must provide proof of the fund's origins? I have to prove my innocence in order to use my own money! FATCA is worse than the NSA -- it's a license to violate my financial sovereignty.
