Swedish tax rates on income makes this two to three times as difficult (approaches 60% plus 30% social paid by the employer this includes RSUs as well, plus 25% VAT) but it’s nonsense to claim this doesn’t happen. I am Swedish and have made significantly more in tech than the author. So has many of my friends.
With that said, the only reason I’m still in Sweden is family. The public sentiment about the future is uncomfortably racist and increasingly hostile about fortune making. If you have the mobility my advice is to move. Good luck.
