Wrong data. You're looking at confirmed cases, which Sweden is massively falling behind on because they're under-testing so badly, as you can see from their absolutely incredible (as in unbelievable) reported case fatality rate of 9%. It's not that 9% of their population is dying from this, it's that they're not even catching 1 out of every 50 people that even have it. Their stats look low because they're so severely under-reported.
The correct figures to be comparing here are per capita deaths. Sweden is currently sitting at 1,014 deaths per 10M people while the United States is at 789. Ergo, Sweden's outbreak is roughly a third worse than the US so far, and growing worse.
