Absolutely not. Marx's conception was that due to the internal contradictions and failures of capitalism, it would eventually and progressively lead into a communist revolution through at some point a revolution.
The proletariat revolution in itself, according to Marx, would be slowly triggered by the advancement of material conditions, that is the evolution of the relations between classes, up until a point where the relations between the proletariat class and the bourgeois class would lead to revolution. The predictions made about the upcoming contradictions of capitalism by Marx have been quite accurate, altough not perfect; he didn't expect them to be.
This specific scenario that Marx was predicting never happened. Late stage capitalism has not been achieved until recently. For example, Marx expected the revolution to happen as all classes would be absorbed into either the owner class or the proletariat class, which has only happened in the past few decades. He also expected it to happen when the capitalist, automating most production, would start to run out of consumers as they would not be employed anymore: we see this contradiction being paliated through creation of demand and creation of useless jobs, which are not sustainable solutions. He also predicted that beforethen, the middle class would be absorbed into either the bourgeoisie or the proletariat, with people formerly of middle class becoming reliant on rent and debt in order to provide for their essential assets. This transformation is in the process of happening.
I am also skeptical of any grand theories of history. However, be fair in your criticism of Marxism. Dialectical materialism posits that eventually, communism would overtake capitalism the same way that feudalism overtook slavery and capitalism overtook feudalism. It also posits, and I think that this is a very good observation, that political economies are based on class relations and that these systems progress, regress or succeed one another by class relations moreso than individual action. Marx's theory could be read to predict that communism will overtake capitalism in five decades or in a hundred. It's core assertion is that the next dialectical shift will be about the proletarian class and it's relationship with the owner class, and that when capitalism is supplanted it will be through the abolition of the relationship between worker and owner through the vehicle of private property. This seems like a fairly rigid theory that holds all possible observations.
