I think if we ever get to that point it will be the end of humanity. I think the desire for more is one of our key driving instincts. It's why communist/socialist regimes can't work. There will always be someone who wants more. Or people looking for adventure. In socialist are communist regimes these people have to be executed or they'll rip it to shreds that's why there's sometimes genocide.
Communism is bad.
But I'm tempted to say it was not this bad.
20% wage losses in 2 generations is more like a Communist failure.
But. This is happening under Free Market Capitalism.
Communist societies of Eastern Europe became more homogeneous after WW2.
Capitalist societies in the Western Europe & the Americas decided to create less homogeneous societies.
Now today Russia is not richer than in the 1980s.
It is Capitalist & filled with Muslim illegals.
Moscow in 1990 was about 1%Muslim.
Today Moscow is 25-30% Muslim.
The Capitalists are the issue.
In Poland the Capitalists in the past years have complained about labor shortages.
As a result nearly a million Ukrainians came to Poland in 1 year.
More & more Chechens, Vietnamese, Chinese etc are moving to Poland.
The issue is Capitalism.
