That's a nice point. Some people in the U.S. do need to be constantly reminded that "Socialism with Scandinavian Characteristics" is not authoritarian or anti-capitalist at all! But that's more like the exception that proves the rule.

Sweden isn't socialist.

Sweden has welfare benefits slightly more titled in favor of the benefit receivers relative to the US. California unemployment lasts 26 weeks (182 days) compared to Sweden's 300 days. The USA provides free education from K-12, and then subsidized post-secondary education. Sweden provides citizens free tuition through college (international students pay similar tuition to American universities).

Everything a Swedish citizen might receive from the government, an American would have an analogous program, it just might have a lower payout, shorter duration or have more bureaucratic hassles to get. But it's not like these are fundamentally different systems, they're the same system with some numbers tweaked.

Socialism does not require an entirely different system, one can implement it just fine in whatever democracy one happens to be operating, so large chunks of it are just tweaking some numbers. And some numbers do kinda make a large difference between having to worry about the bank account running dry before the next paycheck or not or being one fall down the stairs away from bankruptcy.

It also declined somewhat since the ~1970s when it was somewhat more socialist than today. But still it is quite a bit more socialist than the US: the points you already mentioned, plus things like universal healthcare, more employee protection, stronger unions (and unions are not a bad word), more paid vacation days (by law not because one has a nice job) and more public/affordable housing.
