Honestly, I’m under the impression that building a building requires scarce resources and labor, which have opportunity costs reflected in market prices, and maintaining a building likewise requires ongoing expenditures. I would agree that, when someone becomes a landlord, the goal is generally to earn a return on the capital they risk, while facing uncertainties such as tenants not paying rent, changes in government policy, and other market risks. Whether any particular landlord is a good or bad person is something I can’t really speak to.
