I think we are more likely to see a wider variety of socialist schools of thought.
Although Marx was fantastic RE his being the father of sociology, in his own lifetime people with disparate and very differing oppinions to himself tried to borrow from the marxist lable. The exile of the Anarchists from the internationale was an excellent example of how adherance to the lable was more important than real solidarity because the lable itself worked as a platform.
Without the class warfare being a neccesity, you might find that a lot more intentional communities set up by rich people with a disdain for capitalism, could become the face of socialism.
Whilst I disagree with the last part (as an anarchist myself
), I dont think that the potential success of ideas is inherently what makes them appealing.
Bolshevism was prior to the revolution something of a laughing stock in international circles because of how obviously dystopian it would be, something in turn predicted by Bakunin years before.
Fascism not only had to reject a hell of a lot of reality, but uniquely for any ideology failed on its own terms, but briefly dominated europe and still has political power today.
