Unfortunately that’s hard to write in a way that’s interesting, or at least that’s my interpretation. Maybe it would read too much like political and economic theory. And then in the cases where it is done it either leads to things like ‘get away from capitalism’ which many ppl wouldn’t like or just not discussing it much like Star Trek where supposedly there is no money but it’s not really explained how. (And I assume if it were more explicitly socialist start trek would have become as big)
