Røkke, who Forbes estimates has a fortune of $5.1 billion, will cost the Norwegian government an estimated 175,000,000 kroner annually (roughly $16 million) with his departure. That might not sound like a lot of money, but Røkke is not the only wealthy entrepreneur leaving Norway, The Guardian notes.

“More than 30 Norwegian billionaires and multimillionaires left Norway in 2022, according to research by the newspaper Dagens Naeringsliv,” reports wealth correspondent Rupert Neate. “This was more than the total number of super-rich people who left the country during the previous 13 years, [the paper] added.”

Did you catch that? More “super rich” Norwegians left Norway in 2022 than during the previous 13 years combined. The reason wealthy Norwegians are fleeing the country is not a secret.

Following its 2021 electoral victory, the Nordic nation’s Labor Party made good on its promise to soak the rich. Norway is one of just a handful of OECD countries that still taxes net wealth, and the Labor Party increased the country’s wealth tax to 1.1 percent despite warnings that such a move would “trigger capital flight and threaten job creation.”
