Yeah, that is annoying. They should feed themselves. Maybe give them a small plot of land where they can grow their own food on the side? Let's call it feudalism. People still romanticize the antique so much they miss that the medieval period saw quite a few advancements. Why did the Romans not have an industrial Revolution? For that you need a society that actually has incentives to efficiently use the labor available. Like in capitalism where you pay the workers based on hours. And the prerequisite for that was feudalism, the development of cities, start of manufacturing and so on. One economic system leads to another. Not easy to just leapfrog from a slave-holding society into the industrial age.
