They are just capitalist with some welfare, nothing left-wing about them

You must be American to ask something like this.

America is so damn red the rest of the world looks ike a solid shade of blue.

they aren't really left-wing at all... maybe from an american perspective because they have some welfare state aspects like state healthcare? they are still capitalist and any socialised aspects have been diminishing intensely since 2008 in favour of regular old neoliberalism. sweden is literally a monarchy which recently joined the nazi alliance NATO, and the scandinavian states are firmly on the side of the US and imperialism when it comes to geopolitics, as well as benefiting from the incredible exploitation of the global south like any global north countries. socially they have been trending more right-wing too like most of europe, anti-immigrant and anti-queer sentiments rising. nordic socialism was never real socialism, it was a flavour of european social democracy with all the national and social chauvinism and continued exploitation by a capitalist ruling class that entails. and any commendable aspects like i said have been steadily whittled away since 2008.
