The government system is irrelevant to the economic system. This is an aside, but this is equally as ridiculous as saying " well Russia was communist" or " Well Nazi Germany was capitalist" to win an argument.
Things like social safety nets and healthcare that won't ruin your life are things that are objectively good, we need to stop pretending they are bad. Not only that, but we know that it works because of the Scandanavian model. It's like Portugal on with drugs; they used to have one of the worst drug epidemics in the world. In a last ditch effort to fix this disaster, they legalized all drugs and focused more on treating such things as an illness instead of a crime.
The results were remarkable. Does this mean that we need to become Portugal to curb our own problems? No, but it does show that these sorts of policies; this model, has worked. And our model doesn't work and is causing problems in our society, so why not try something that has worked for other people.
The same is true of democratic socialism. Homelessness is a hard thing to fix if you just expect companies to fix it for you... Same thing with all of the homeless people with mental and physical health problems, less social safety nets for families and children so overall environments become more intense and children are more likely to suffer, I just don't understand why you would be so " this is what we need" on the grounds of denying data on the count of a population size?
The Swiss example is almost funny -- this is how the counter-arguments always go, as if there is nothing about Switzerland that makes it different to the rest of Europe. I mean for starters they are semi-direct-democratic, and furthermore Democratic socialist -- they have free healthcare and many other prominent social welfare infastructure. They are heavy investors in public transportation, public services, and schools. I think we have a lot to learn from Switzerland, but it's not the privatization that they benefit from as much as it is colonial and precolonial contexts -- how they became neutral, how they came to store so many people's money, and how they became a buffer zone that avoided most global conflicts.
