No defense for landlords or anyone else for that matter but the trend of landlords being hostile to tenants is part of a larger trend I see all through society and its one of tunnel vision brought on through experience. This is to say that when one is engaged in an activity for a prolonged period of time that experience seems to cloud their judgment ie if all you have is a hammer etc. Anyone who has worked a cash register may sympathize with the observation that all customers are stupid assholes. Police officers only see the worst behavior, teachers who have taught elementary school for decades lose ability to communicate with adults, landlords who only rent to low income start to think everyone is a deadbeat. The list can go on. Are these generalizations absolutely and I’ve experienced them all enough times personally to generalize. The remedy is to change our activities and keep a critical and open mind. The older I get the more value I see in liberal education in the classical sense.
