From the article,
Every country on the planet with high real median personal income also has billionaires. It is at least plausible that there is a connection between institutions that make billionaires possible and the same ones that create general prosperity. In fact, Sweden has more billionaires per capita than the United States. Perhaps not coincidentally, Sweden is just one of dozens of countries that have tried wealth taxes and abandoned them.
