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.
$82k is $4.1k take home (with healthcare) as a single in Germany.
$168k is $8.8k take home as a single in Portland.
Let's say monthly expenses are $1.5k as a single in Leipzig. According to numbeo I would need $2.5k for the same standard in Portland.
So in Portland I can save $6.3k or 2.5x my expenses and in Leipzig I can save $2.6k or 1.6x my expenses.
Healthcare is included in the net pay for Leipzig, but not Portland. Employer 401k contributions and other benefits are also not considered.
Other things to consider are safety, unemployment, workers rights, tenant rights, quality of healthcare, cost of elderly care, government retirement plans, PTO, sick leave, maternity and paternity leave, cost of childcare, etc.
Really comes down to what's important to you IMO.
