Management is a real thing, a technical matter. But it can be controlled by labor just as well as by capital. Capital itself is simply the useful residue of the work of past laborers, and it could belong to everyone as well as to a few. There is no reason why a tiny nobility should own the capital, and everyone else therefore be in service to them. There is no reason they should give us a living wage and take all the rest that we produce.
-Blue Mars (Kim Stanley Robinson)
