I get 30 paid vacation days, 10 ish public holidays and my employer has to pay up to 6 weeks of sick leave a year (after that the public health insurance pays).
I make around 75k€ with a 38 hour work week and my take home is roughly 3600€ net. My living expenses are less than 1k (mid sized city, no car, split rent, no kids) so I am able to invest 2-2.5x my living expenses every a month.
Germany may be good to live and get by but not great to actually grow, financially. The whole system is still designed so that you depend on your 800€ gov check in your senior years.
Unless your parents already built some wealth it is barely possible to do so in your own lifetime in Germany.
