It is so hard to even contemplate giving up my citizenship in America. And you can’t escape the taxes without doing so..it’s a tough call.
And the problem is, if you’re of some means, you really can’t escape the taxes even with expatriation as a US citizen. By locking the “earners” in the society, almost irrevocably to their US taxation for up to 10 years the wealthy are going to dig in their heels eventually.
Expatriation becomes more problematic as a person’s wealth increases.
