Social security fees are added on top of gross salary (and normally not visible on your payslip) so it's not a tax per se but still a cost for the company.
That's not just taxes, he/she is including pension, healthcare etc. on top of not just employee but also employer taxes.
Since the pension is mandatory it’s essentially a tax to pay for a government provided pension. Same goes for everything else.
> No way taxes are 66% of the gross salary.
In EU countries, there are many taxes that do not carry the official name "tax".
Much easier that way to get the people to swallow the pill.
