Imagine a society where one person produces all the value. Their job is to do highly technical maintenance on a single machine that is basically the Star Trek replicator: it produces all the food, clothing, housing, energy, etc. that is enough for every human in this society and the surplus is stored away in case the machine is down for maintenance, which happens occasionally. Maintaining the machine takes very specialized knowledge but adding more people to the process in no way makes it more productive. This person, let’s call them The Engineer, has several apprentices who can take over but again, no more than 5 because you just don’t need more.
In this society there is literally nothing for anyone else to do. Do you think they deserve to be cut out of sharing the value generated by The Engineer and the machine, leaving them to starve? Do you think starving people tend to obey rules or are desperate people likely to smash the evil machine and kill The Engineer if The Engineer cuts them off? Or do you think in a society where work hours mean nothing for an average person a different economic system is required?
For something to be deserved, it must be earned. What do these people do to distinguish themselves from The Engineer’s pets? If they are wholly dependant on him for their subsistence, what distinguishes him from their god?
To derive an alternate system you need alternate axioms. The axioms of our liberal society are moral equality and peaceful coexistence. Among such equals, no one person, group, or majority has the right to dictate to another. What axioms do you propose that would constrain The Engineer? How would you prevent enslaving him?
