Good thread, Hawkeye. Every 6 months or so, when the radical liberals in Washington state (where I live) pass yet another piece of insane legislation, I start to think about where I can expat to. One of these days, I'm going to make good on it, but have yet to decide where to go.
The US is still the #1 economic and military power in the world, and there's no other country with a similar status whose currency can replace the dollar. That's why I don't see a collapse like the one you're predicting, but rather a decades long slow and steady decline in which we continue to lose our civil liberties, while the cultural Marxist, feminist, homosexual, and negro-worship agendas continue to march from one victory to the next. The country is already unrecognizable from 10 years ago, can you imagine how bad it will be in another ten? But where to go?
With the exception of Germany and Switzerland which you have already mentioned, Western Europe is out. They're being overrun by Muslims from the Middle East and Africans from every part of that hellhole. Australia and Canada are actually worse than the US when it comes to the feminist and PC agendas, and they're being flooded with Pakis, Indians, and the Chinese, plus they get their share of Africans as well. If you have been paying any attention to the Roterham story and the way the UK is being transformed in unimaginable ways, you know that the Pakistani scum is the worst of the bunch, right up there with the negroes.
Argentina and Uruguay are both around 90% white, but the economic and political instability seems to be a way of life there. But if you learn the language and have a trade/skill that will always be in demand, those two countries top my list. They are as close to negro-free as you can get and the overall quality of life is pretty respectable.
If you're going to stay in the US, best bet is to live somewhere up North, maybe buy some farm land and unplug from the matrix. Unfortunately, that option doesn't work for me, so I'm stuck at the moment.
