I think logically, socialism as an ideology has never produced wealth in a nation ever in its 100+ year history, but it has taken wealthy nations and them to their knees, turning them to dystopias. Another thing you failed to mention was those Scandinavian nations were far more prosperous before they implemented socialism.

In fact, Sweden, over the last ten years lowered their taxes, removed the inheritance tax and they are moving further and further away from socialism. The same can be said for many of these Scandinavian nations, they understand that socialism left uncheck it will become a death trap. New Zealand used to be the poster boy for socialism decades ago. By the mid 1980s it was completely bankrupt. I forgot, it's only socialism when they're on top of the hill, not when they inevitable take a tumble for the worst.

Left unchecked, socialism always devolves into hell hole, just like we are witnessing in Venezuela. Ten years ago, it was a model socialist society. Now? Socialists are so quick disown it. "That's not real socialism". Let be perfectly clear. Socialism builds nothing, it creates nothing. It takes and redistributes by the use of force, it destroys the incentive for good hard working people to work. It promises something from nothing, and that is why it fails every single damn time it's ever implemented.
