Some issues:
Payouts for top talent are not great. Compared to US, you rarely get stock based comp or salaries higher than $80k/y and even then most of it goes to taxes. That is not unique with Sweden though, it's EU in general.
Second. The weather is not for everyone.
IMO that puts a cap in the potential growth as only the top companies can attract and pay the talent (Spotify Klarna, iZettle etc.).
