For-profit museums aren't really a thing in Sweden either, because you won't be making a profit, unless you're the Vasa Museum, but even that is struggling.
Museums are sort of like farms in that you can lose money every year for entire lifetimes and still have a tremendously valuable farm. Like land, the past is an appreciating asset. That's big, traditional museums. I suppose it should be no surprise that the smaller museums are still struggling in the post-covid era. I based my opinion on visits prior to the pandemic, so I'm out of date. Hopefully the popularity of museums in Sweden will rebound.
