This is, on the whole, bullshit.
Compare that to even a current PhD making 3k euros per month with house prices starting at 300k for pretty bad (certainly not newly built) and smaller than the one their parents had, and they find they can't afford it on 2 full-time wages.
So "quality of life has dropped dramatically". Yes. Yes it has. In other ways quality of life has advanced, yes, but the basics ... the basics are a disaster.
And this is the situation in the most economically prosperous side of Europe. Ireland, the Netherlands, Belgium, Nordics, France, Germany. If you do the same comparison in the middle or south of France, Northern Italy or Spain it'll be 10x worse. If you do it in Portugal, Southern Italy or Greece, it'll be 100x worse, hence everybody is leaving. And if you do it in Eastern Europe it'll be even worse: everyone (who even remotely can) HAS left.
Then the entire West started buying cheap from China and imposing rigid environmental constraints locally, and manufacturing jobs left forever.
However the language you use is exaggerated to the point of hysteria, which kind of undermines everything you say.
Also, your original point was about immigration. There is a housing crisis even in countries with relatively low levels of immigration, which indicates that other factors are at play.

While there are high levels of emigration in these places, what you're saying is exaggerated to the point of being bullshit.
