I'd recommend reading far more than The Communist Manifesto to understand the issue better. You're not describing Marx's conception and predictions of communism at all. And you seem to have misunderstood the Manifesto as the definition of communism. That was not its purpose. Its goal is to wake the consciousness of the working class to their condition, explain why this is important in simple terms, and suggest an immediate course of action for helping move society away from capitalism and toward communism. But the Manifesto was not a description of communism itself. For that, you must set the Manifesto aside and dig into Marx's other works. There is no state doling out equal portions of anything to anyone under communism—because, most critically, there is no state.
