Last year in Sweden, I compared paystubs with a colleague there.
His take home - as a percent of his salary - was within a few dollars of mine.
Meanwhile he doesn't have to worry about health copays, deductibles, etc.
But you don't have 25% vat on most items... and massive taxes on food/achohol and all kinds of social 'steering' taxing.
Those societies don't have obcene income taxes on the middle of the pack.. it's on the high earners. They basically try to lift everyone to a good median level... and get more extreme the further you get away from the sweet spot. They aim for high quality of life, and excess is taxed excessively.
