IDK do we still consider china - a country that currently has a fairly enormous middle class - to be communist? For that matter, do we view the current american economy to be a free market? (It's certainly "capitalist" in the strict academic sense of the word, wherein capital invested is the means by which ownership is ascertained, but that's generally not what people mean colloquially, so I find that using that term mostly bogs people down in semantics)

Furthermore, why do you believe that the only possible outcome of class solidarity is violent revolution? Why do you believe that any revolution would inevitably settle on, presumably, a specifically soviet model of government and economic policy? I find that most american adults, even ones who otherwise seem intelligent, seem to have this picture of economic and power relations that just kind of sounds like a half-remembered bad cartoon of a cold war that ended before I was born.

Whatever China's regime is now, it is the expression of a population with a much more collectivist spirit than the West, a population that overall (i.e. a small dissident minority aside) is willing to submit to the Party in the name of social stability. The West is a lot more individualist, and a revolution under those circumstances is likely to be much messier. The point is that it probably wouldn't neatly land on a specific model, Soviet or not, but would first involve immense turmoil and infighting like revolutions usually do, and after that it still probably would never reach the effectiveness of China's post-Mao model.
