Clock's been ticking for a long while now on Denmark, Sweden, Norway, and Finland. When will you give up waiting for these socialist states to collapse?
A socialist country is one in which the means of production aren't privately owned. If most private businesses are illegal, that's socialism.
The Nordic countries aren't even attempting to ban private businesses, or claiming that as their goal.
The track record for countries that call themselves socialist is pretty grim, on the other hand.
You can't use "socialism" to mean "Venezuela, and only Venezuela (well, maybe Cuba)" and then "anything that gives more power to the US federal government". Choose one. (I'm not saying you do, but so many people do.)
From what I've seen, many people who believe the "danger" of socialism are also quite convinced that the US is in the danger of slipping into socialism. Why that doesn't happen in Sweden is left as exercise.
By that account Venezuela was certainly not a socialist country.
Under what definition are these socialist states?
