As I already demonstrated, in this very thread, no. We have dozens of prosperous socialist states in western Europe, not a one of which is in a pre-cursor of communism position, and pretty much none of the communist states slid a slippery slope of socialism to get there, they got there through violent revolution or from being occupied by an existing communist state. And violent revolutions, by the way, historically have happened in places where there was huge wealth discrepancy and wealth concentration...that actually is true. It's decidedly NOT wretched to live in Finland or Norway, or Iceland, or France at the moment, while it's not fun to live in Looneyville, WV (real place) and pretty damn wretched to be living in the slums of capitalist Brazil. I've pointed this all out to you before, and your only answer is point out a definition of socialism that only you seem to hold which the rest of us call communism. So again, are you just trying to be argumentative, or do you truly believe that Norway has little hope of not morphing into a communist regime and can you please point out literally anywhere in socialist Norway that is as wretched as much of capitalist Rio?
Europe is not socialist and all the states in this continent and Scandinavia became rich enough to adopt some semi-socialist policies through capitalism.
