In neither Norway nor Sweden are the means of production owned by the state
Some people believe these are socialist states. That's a misunderstanding of the term socialism (just as it is grossly misleading to call systems such as the British health care system socialist).
It's more accurate to say these are capitalist states that use some of the surplus resources generated by their capitalism to fund social programs (such as the kinds of things you mentioned in your list). This does not make them socialist.
It's also worth noting that these small states depend in part in capitalism in other states with larger economies, since they can't even come close to funding the kind of research and manufacturing that the bigger states can, which affects all kinds of things (like health care). In a sense, they mooch off the larger capitalist states. If they had to fund everything themselves, they would not be able to provide high quality social services over the long term.
I'd go further and say that is it misleading and dangerous to claim these are socialist states, it simply encourages the true socialists, who stubbornly refuse to acknowledge that socialism (as it is classically defined) has been tried many times over the past century and more, and has been a massive failure every time. Encouraging people this deluded is never a good idea.
Alternately, we can think of calling Norway and Sweden "socialist" as falling prey to socialist propaganda.
In fact, not only has socialism been a huge failure, the most successful anti-poverty or welfare program in the history of the human race was the Chinese switch from socialism to capitalism, which brought millions of people out of poverty. Similarly, India (while it still has a long way to go) has seen huge improvements in the standards of living of much of the population since switching from socialism to capitalism.
The right path forward for humanity (in terms of the greatest good) does not involve switching from capitalism to socialism, it involves for each nation figuring out how much of a nation's production can be allocated for the general good, then trying to spend those resources as efficiently as possible. Also, just as Adam Smith noted, some regulation of capitalism is necessary for the greater good.
If a nation takes too much of it's production to spend on social causes, it goes into debt, which is likely to cripple it over the long term (something the USA and Britain are struggling with now, yes I know the USA doesn't spend it's resources well but that is a separate issue).
There are two fundamental issues here that the true socialists do not want to understand, namely 1) that production is very inefficient under their system, and 2) that taking too much of the production of any system to fund social causes cripples the system and hurts everybody (creating a welfare state and/or massive levels of corruption). This is why encouraging socialists is a bad idea. Instead we should be focusing on finding a reasonable level of production of allocate to social causes, and then paying attention to spending that production with a reasonable level of efficiency.
