I'm not sure why people get so vehement about denying this fact. Perhaps because it requires acknowledging that socialism actually works really well?
I think social democracy is probably closer.
There's free enterprise and the government owns some part of some companies.
I gues this will help you to understand:
"Ownership: In a capitalist economy, property and businesses are owned and controlled by individuals. In a socialist economy, the state owns and controls the major means of production. In some socialist economic models, worker cooperatives have primacy over production"
Finally, no socialism never has been working very well. There is not a single example of it working well in all recorded human history.
I guess if you define "socialism" in a sufficiently narrow way you can ensure that no existent successful country will meet the chosen definition, a clever rhetorical trick.
This is not the definition of socialism.
"The Nordic model refers to the economic and social policies common to the Nordic countries (Denmark, Finland, Norway, Iceland, Greenland, the Faroe Islands, and Sweden). This includes a comprehensive welfare state and collective bargaining at the national level with a high percentage of the workforce unionised while being based on the economic foundations of free market capitalism."
