@goatsarah We almost did leave in 2001. Had the American INS approved Mrs Wife's work visa before 9/11, we'd probably be out there to this day.
And so I've watched not one but two great countries deteriorate over the last couple of decades. Since about 2015, on balance, I've been glad we stayed put.
If we were planning to leave now, the first question would be: where? The EU is no longer open to us. How do you pick a country that won't end up worse than where you are now?
