Saying this devalues the world, though. Anytime someone diverges the conversation with "It's not real life, so why should we care?" completely devalues a story. Sure it's fictional, and anyone can just say "X = Y" but it's not valuable unless it's believable and enjoyable.I dont get why we are getting physological and historical talks about slavery and stuff..
Its a fictional world
If Runey says slavery is profitable in his world... then it is.
Fiction!
Slavery is just profitable. The less people pay workers, the more those people get. It's all about the money, and people will do whatever gets them the most.
In the US, the minimum wage is about $7.50 something. Most companies can afford more but don't pay more because it's less profitable. If they could get away with paying you nothing, and it was legal, they would. And did in the past. Now it's widely accepted to be wrong though.
