Marx theory is about the fight of classes in society. There is nothing predictable about how this fight will happen. The only prediction is that in the end only one class will remain. It cannot be the bourgeoisie simply because they don't work! Moreover, even if only the bourgeoisie happened to survive without work, their instinct is to kill each other (economically) until only one remains. So his observation, that the final state must be some form of socialism or total destruction, makes complete sense.
