There are two problems with this line of reasoning of the type of muddied thinking you're replying to. The first is that it can both be true that supply and demand as a phenomenon can be used to meaningfully explain the world and applies to housing, AND that an individual can denounce landlords morally with the phrase "greedy". However, the OP cannot reconcile the two concepts, they said.
Next, the idea that landlords are a unified group with a common set of designs is itself a premise that requires a little bit of legwork. Here's one. What are landlord expenses versus their expenditures. Are they large or small landlords. etc. To hell with nuance, let's create an Us v Them type of discourse, and see who bites.
