There are no European countries that are communist anymore.
The only communist country that has ever done well economically is China, and that was after they threw away socialist dogma, and allowed capitalism in their economy.
I live in Denmark, which is part of Scandinavia, and we have been using the social democratic model since 1924 when we got a social democratic prime minister, who is also our longest sitting prime minister with 15 years.
Yes we are seeing an unfortunate turn to the right in recent years, as I mentioned before, probably to a large degree because of Immigration from the middle east. Where the right claim they will stop immigration. But probably also because we have seen socialism/communism is a failed model that simply doesn’t work.
Social democracy on the other hand does work pretty well, and is probably the strongest at protecting the population and observing human rigts. But currently people don’t want a humane government, they want the immigration to stop, because it threatens our democracies and economic model with a high degree of social welfare.
