Marx's class analysis was basically sound but his predictions were wrong. Perhaps we've not really understood what he meant. In industrial countries, most Marxists aren't revolutionary. The government of a country which has had a dual revolution is much harder to overthrow than the government of one which hasn't . As mentioned in the discussion of democracy, Industrialization significantly strengthens the powers of states by giving them enough material strength, economic power, and technology to affect the everyday lives of their citizens.
Democracy gives states increased strength by harnessing the energies of the masses for the state.
If imperialism ends, Western economies will get harsher again, and the proletariat will revolt.
