Just in case anyone still thinks that Sweden is a modern example of a successful socialist state, they may want to give this article a read.
Socialism (or any other form of big government) requires that a small set of adults compel another much larger set of adults to shut up and do what they are told. Is there really any mystery about why socialist states fail to generate flourishing societies?
A very large majority of the world's population live in poverty. That same very large majority of the world's population live in societies based on compulsion of the many by the few. Ah, duh.
History remains utterly clear about what works and what doesn't when it comes to human interaction. Voluntary exchange succeeds. Compulsion, regardless of the form it takes (dictatorship, socialism, communism, democracy), fails. Voluntary exchange is moral; compulsion is immoral --- just an additional benefit of voluntary exchange.
