House prices : salary ratios are much worse in the EU (because salaries are so much worse in general), and housing is much smaller (no room for hobbies, home gym, usually no AC, etc. - which is awful during the recent lockdowns). Gas/diesel prices are much worse too (and driver training, car insurance, road tax, etc.) so car ownership is much more expensive (and severely regressing compared to prior generations).
Electricity is much more expensive, so is food, vehicles, electronics, pretty much anything you can think of. Salaries are lower and taxes on income (not property/inheritance, etc.) are much worse. And all of this is set to get worse next year with prices, inflation and income taxes going up and salaries not shifting (there has been no "Great Resignation" here).
If you want to see the death of the middle class, just look at Europe. With low home ownership, prospects are much bleaker for any sort of retirement too.
