So in your opinion, if government didn't steal half the salary, the employee would still only get what they get now?
When I ran a company, I paid the employees as much as possible, to ensure that they didn't leave to someone who paid more. From my PoV, income tax is paid for by the employees, and so are all the additional social fees (in Europe) on top.
A Swedish corporation started to put ALL the taxes on the payslip, and was outlawed immediately.
