We haven't been anything like Cuba or Soviet at any time. We never had 5-year plans or Kolkhozes or anything even close.
The "monopolies" that existed were inherited from the time when the King ruled the country. Railway? "Royal railroad" founded in 1856. Mail? "Royal Mail" founded in 1636. Telephone? "Royal Telegraph" founded 1853. And so on. They kept doing business as usual when the King was ousted, just that the King was no longer running things (he never did, it has always been civil servants in charge), but the state. They were the largest in their field, but certainly not alone.
We had private alternatives to both mail and railways long before the huge old government owned companies were sold out, but we still have government owned huge companies, but they have to compete on an open market.
I'll gladly acknowledge that the last 30 years have seen more sellouts than at least I would've wanted, but the "socialism" here was never about owning, but making sure people got a fair salary.
We never had a revolution where the people took over means of production. Instead, "the Swedish Model" established in the 1930s rely on unions and collective bargaining. 88% of salaries are decided through collective bargaining. Employer federations and labour representatives bargain at the national level mediated by the government. For example: we're not allowed to go on a strike unless it has been decided by a union. Rail workes went on an 3 day unsanctioned strike last week in Stockholm. They are now being charged in court for "unlawful strike" and will have to pay a hefty fine, individually.
Around 30% of the workforce work in the public sector (myself included), compared to around 18-19% in the US.
Public spending is at 56% of GDP in Sweden, compared to 37% for the US (and we have a puny military in comparison). Tax burden is at 44% of GDP, compared to 19% for the US.
To quote wikipedia:
"Some economists have referred to the Nordic economic model as a form of "cuddly capitalism", with low levels of inequality, generous welfare states, and reduced concentration of top incomes, contrasting it with the more "cut-throat capitalism" of the United States, which has high levels of inequality and a larger concentration of top incomes, among others social inequalities."
We have never been "hardcore socialists", but have not embraced capitalism fully either but instead tried to be inbetween. The main goal has always been about fighting social inequalities, the thing that almost ruined Sweden during the 1800s. We've had private alternatives for ages, its just that we've gotten more of them in recent time, but the goal of fighting social inequalities have not changed, money is being "taken from the rich and given to the poor".
