alt Hacker NewsExample from Germany: Employer also pays a share of health insurance, unemployment insurance, public pension and elder care insurance.
This is not visible on your payslip, i.e. if you earn 5k€ brutto, the employer has to pay these shares on top of that.
But that is 20% not 100%. And in most non retarded countries brutto is actually brutto, because there is no need to lie to people about how much the government takes away
