Great analogy..I agree.

Reminds me of The Eagles' Hotel California... "You can check out anytime you like, but you can never leave..." Our Dear Leader and his regime are making it tougher for his subjects to flee the oppression being imposed upon them.

So, the communists are importing illegals & then will grant them "amnesty" ~ for freeeee. (what movie is that from? Anybody?) But yet, when the Producers have something lined up & have had enough, the same communists want to rape them on the way out.

We are witnessing the near completion of the communist revolution here in the U.S. And don't tell me 'Let's vote the bums out....' Don't make me laugh. The voting is rigged. Don't believe that, or better yet, want proof on how our voting doesn't matter.? Read Chapter 12 " The Eternal Power Behind The Throne" of The Rockefeller File by Gary Allen, circa 1976. He explains it all.

I believe you're correct!

Has it really become that much more difficult to raise the iron gate leading beyond the wall?

Is this the financial equivalent of the Berlin Wall?

So, FATCA starts monetary controls, so this starts people controls. Like Burger King, Canada sounds better and better but has the big problems of being a good neighbor that happens to be surrounded by the US. Maybe somewhere in Central or South America is better.

I agree with the sentiment of your post.
If you don't have any tax liability from income then you are probably correct. However, if you want to have the legal staus that supposedly prevents the looter scum in the Dark Center from stealing your earnings and eventually stealing your assets from your heirs, then this is the process you must go through. The looters have an army that currently includes almost all the bankers in the world and many of the police/military of US allies. They will not hesitate to set the dogs on you IF you have assets worth stealing. (It may be posible to place your assets in trusts to protect your heirs inhertitance without this process, but I think that involves placing your trust in someone else to manage those assets.) There may be other legal means to achieve the status of non-citizen, but I am not aware of anyone with assets worth grabbing having done so.
I suspect that the definition of 'citizen' may actually be synonymous with 'subject' in the United States today.
I don't like it any more than you do.
