the most effective being the "Scandinavian model" countries which effectively blended large amounts of socialism into a capitalist system

That is absolutely NOT socialism. Like, at all. And if you legitimately think that, I'm genuinely sorry to say that you are quite unclear about what socialism is.

The Nordic countries are absolutely not socialist in any shape or form. They are very much capitalist societies with marginally better welfare systems. Which is not saying a lot considering the average country that leaves every individual to fend off for themselves.

They all have staggering amounts of regulation.

I was being overly simplistic in my original comment I admit. They do have regulations, but know this: "regulations" in a capitalist system are always limited in their scope and are primarily designed to sustain the capitalist system to allow it to perpetrate its profit-first essence. By nature, they are never created with the intent to actually challenge or limit their fundamental exploitative dynamics (think of the 2008 crisis. The banks were bailed out and measures were put in place to stabilize the market. And yet no serious measures were put in place to fundamentally change the market itself or to prevent future exploitations).

I sincerely hope you might use this conversation as an opportunity to read and learn more about Socialist/Marxist theory. I am convinced far more people would agree with it more than they think (especially in these fucked up times) if they'd read more about it
