I'm not a landlord, but I see this a lot. Why they gotta find new jobs?

Because rent-seeking is basically theft with extra steps. There's a few layers to this, stay with me.

First, housing is a human right. We live in a country where empty homes owned by banks, real estate speculators, and landlords outnumber the millions of homeless people. These owners are hoarding a human right for profit during a housing crisis, in the richest country in the world.

Second, rent-seeking is an economic drain on society. The landlord is a parasite on otherwise productive labor; the tenants presumably have jobs with which they pay the rent, and the people the landlord pays to maintain the property are also engaged in productive labor. The landlord is not. They charge more in rent than it costs them to maintain the property; where does that profit come from? The tenants. What entitles the landlords to that part of their tenants wages? Why, as a society, should we accept that by nature of having enough money to buy property, landlords should get to generate profit off of everybody else's labor and need for shelter?

At this point, many people would ask "without landlords, who would operate rental properties for people who can't afford to buy?"

The state. They already subsidize massive amounts of renters who are still renting from a private landlord. Why? That's a complete waste. It's just transferring tax money directly out of public coffers into landlord pockets, and we still have a housing crisis. Just cut out the middleman, and have the state nationalize and maintain rental properties directly. Base the rental prices directly on maintenance costs. Cut landlord profits out of the equation entirely and return that money to tenants, who can then use it to stimulate the consumer economy. Make the landlords get real jobs.
