But we're not talking about obscene amounts of money. Just making enough to have some savings so you can do things like a career break or retire early is discouraged (and mostly impossible). Europe wants you to work, and keep working, forever.
Considering the differences in living prices in major capitals and other cities, I would claim you can do that (career break/retire early) even today in multiple countries in Europe.
But that would mostly mean changing places. If you go and work 10-15 years in an expensive/high pay city, you could retire in a less expensive city.
On the other hand if you expect that everything will be as when you were working (place, expenses, etc.), I am not sure it is the case even in the US for early retirements ...
