I wonder what would happen if a similar invasion happened to the UK, where I live. I don't know what it's like in other so called "first world" countries, but at least here there is a housing crisis, as in nobody can afford them. Even with the economic destruction over the past 2 years, house prices have only increased. Now the cost of living is rising faster than ever, and interest rates going up will only compound the problem with people not being able to afford mortgages.
My point is, if your home isn't even your own, then what motivation do you have to defend it? The people at prime fighting age can't even afford to say they have their own place, their money is funneled to property management companies, Jews, Arabs, rich people. None of which I expect would hang around if they could actually afford to leave.
Burgers, is it similar over there?
