I forgot a BIG reason why Sweden is not and never has been "socialist".

No five year plans or anything like that. Because it was never a centrally planned economy and the government had to be re-elected every 3 years. There was always a risk that they would not get re-elected. So, making a 5 year plan was impossible.

They made some "special" plans for stuff like housing and healthcare and set them up in a way that no future government could change it.

But it was not a Plan that governed everything, like the ones that the real socialist countries had.

I think Marx said something to the extent that a socialist economy must be planned by the representatives of the people, outside of the reach of manipulation by capitalists. This never happened in Sweden, instead there was a symbiosis between the capital and the state.
