Why were those "rentiers and parasites" ever involved? Why wasn't the NYT (or any other Thing) just created by the workers without their involvement? The answer in practice is that they provided value by providing the necessary capital to build the thing, and they did so in return for a cut of the future wealth earned by the thing. It's arguable that the wealth inequality that set the initial conditions for this is out of hand, but given the starting conditions, how else do you make big things?
