[Hikikomori]

The obscenely rich in Sweden are for the most part so because they own companies that grew a lot in value, when their stock was issued its value was low so they paid very little taxes on it. If they sell stock they pay 30% on profit from it, which is not a lot of tax on possibly billions.

They may also avoid selling by taking out loans instead, and just pay interest rather than any taxes.

This doesn't mean that the rich are not paying taxes or are not paying for a larger % of taxes in total, but they're far from paying their fair share because most of their wealth didn't come from income. Regular employees have higher effective tax rates, even more so if they're issued RSUs.
