Your US citizenship will chase you abroad, make you file more crap than and get you more closely watched by the US than can even be done illegally domestically, all while preventing you from using banks and blocking you from standard investments both in the US and abroad.

Gone are the friendly (in retrospect) days of "if you don't like us you should leave."

From other nations with sketchy governments, you can claim asylum status where you land. For US citizens, you will be assumed to be crazy if you request status. You may as well be as no US citizen is able to prove their own prosecution. If the FOIA keeps any teeth it is still ~30 years after death that a FOI request will show anyone was politically targeted by the executive branch like Martin Luther King.

Enjoy your GDP, but try to stop spending it all in one place.
