Sweden has a large ratio of billionaires relative to the rest of the population, and they aren't leaving. It's 14th in the world by number of billionaires, 7th per capita [0].

Rich people here pay a flat 30% tax on capital gains so they usually pay less taxes relative to their income than a salaried person earning >45-50k SEK.

There's no wealth tax in Sweden.

I don't think you know much about Sweden's tax system (or even in general) given this comment.
