That's mostly because the people running them are interested in making money and maybe aren't doing it with the same passion. Besides, I'd say logistics, being something that critical to modern society, would be one of the things included in that 20 hour workweek I mentioned. People would still have jobs, but they'd be left with so much more free time than they do now, time that wouldn't need to be spent on side hustles and the likes because society would be geared towards covering needs, not making money.
