In Germany getting 25k as a working adult is hard, because before taxes and social security that's 50k you need to earn. Thats more then an average person earns in a year before taxes, so they'll likely be saving for 5-10 years if they want to start one.

Now wherever that's an issue with the 25k admission fee OR with the fact that wages have stagnated for about 25 years in Germany, consequently mostly wiping out the middle class ... That's debatable.
