Okay, but this is not at all what Marx himself said. Marx was philosophically opposed in all of his writings to answering even the most basic questions about what a communist economy/government would look like. In his mind he was only proclaiming the inevitability of such a system. In fact, he regularly dismissed anyone who asked these types of questions as serving the bourgeoisie.
But it turns out that, after a socialist revolution, who is going to make the bread and who is going to distribute it is not a problem that will inevitably be solved.
