Go to https://www.nettolohn.de and enter 64000€, choose Berlin, keep the rest. That's not enough for a modest lifestyle for a family, proven by the fact that with such an income, you're already entitled for social benefits (Wohngeld) in an average German city of 200.000 inhabitants for a family of 4: https://www.wohngeld.org/einkommen/#Wohngeldtabellen_fuer_Mi...

This is the government telling you: you can come work full time for us, but you'll not be able to provide for your family, that's why you can stand in line with all those who don't work at all to claim your benefits.

Assuming you don't pay Kirchensteuer, it's almost €40,000.

> you're already entitled for social benefits (Wohngeld)

No, you're slightly above the threshold but in any case this doesn't say much. If you're talking about families, I'd also assume that your partner earns a little extra.

Anyway, the median gross income in Germany is €54,000, so you seem to be implying that the majority of Germans are unable to live a decent life. Maybe you should talk more to people outside your social bubble?
