>This pretty much happens already in progressive taxation countries(e.g. belgium) where you can actually make less money by having a higher salary because your tax-rate increases.

All sane countries with progressive taxation always apply the higher tax bracket only to the part of the salary that is in the bracket.

E.g. if the tax is 10% < $50k and 25% >= $50k, a $60k salary would have to pay 10% * $50k + 25% * $10k in taxes, and all wage increases increase net pay.
