The word is "exploitive". Desperate people will do things because they have to. If I pay a homeless person $20 to humiliate himself, is that a fair transaction, or an exploitation of the asymmetry between our conditions?
If you call 20$, for a person who owes nothing and is probably starving, a "short term profit", you've very likely never experienced how is it to live in poor conditions.
> Sounds like $30k is an improvement in their lives then, so is it really "too little"?
Being put in prison is an improvement for many individuals in so far as they are guaranteed three square meals and a warm place to lay their head. Would you seriously argue that that's an improvement that is worth the cost to the individual?
