Where is more than 50% coming from? If you aren't married your effective tax rate is at 42% (tax plus social deductions which aren't technically taxes).

Tons of tax calculators available online, see for yourself.

> you never cook yourself?

I do cook but it's not like groceries are free. And what about saving for an emergency fund, a downpayment, a vacation, a new PC, laptop, phone. Or, god forbid, a car?

Do you feel safe and stress-free paying 51% of your take home comp just for rent? And keep in mind, 80K eur is top 1-5% salary.

The overwhelming majority doesn't make that much.
