I asked a feral human (which really, takes some doing) and he explained that by corralling the rich people into the cities, and getting them to help push out the feral -- well, it made the rich people easier to harvest or, more commonly, cull for meat. I offered that, well, if that is the motivation, then you can hardly call yourselves feral any longer for, clearly, you've developed animal husbandry. He conceded that I was probably right and that, for pointing out his error, I deserved some reward. So he gave me an approved lease on this apartment in the city! And I'm not even rich!
