Hey I feel you. Same category.
The gist: If you didn't inherit, you are fkd in Germany.
MOST of wealthy people inherit it (and 2/3 of super wealthy inheritance in Germany is former Nazi money). It's unfair.
What helps me get by: I know my life is good, even though exiting the treadmill is most likely not possible. Enjoy what you have, invest a bit and focus on things that make you happy :)
