It's a morally questionable situation, but I wouldn't put the blame and responsibility on the individual renters/landlords. The flaw is in the system that incentivizes and perpetuates such a situation. The people involved are simply rational actors in that system. Problems aren't solved by just hoping everyone acts more morally, but by redesigning the structures and incentives that shape both the outcomes and our values.
