Actually... Sweden has a large loophole for extremely rich people. Stick it all in a "Capital Insurance" product and pay a low yearly tax on the amount, rather than the gains.

It kind of makes Sweden into a low tax haven if you're only living off capital.

Income tax and capital gains tax are two different things and two different rules sets. In Sweden income tax is max ~56% while max capital gains is 30%.

Don't forget to add the "totally not income tax" aka arbetsgivaravgift at another 30% :D

That does also not apply to capital gains.
