Just because landlords have existed thousands of years doesn't make the situation right. There are lots of harmful things society has been doing or did for thousands of years. Feudalism isn't one of the high points of humanity, to say the least.

If he lived in his primary residence and did honest, productive work (Or hell, even just collect disability, pension, SS, every damn cent the government will give them, I'm all for that!) There would be 3 more houses that families could buy as primary residences (in an ideal world). Yes, I know there is nuance, PE firms like Black Rock and speculators will probably buy some of them up, etc. etc. so you don't need to "actually" me here, just work with me here on the ideal that those houses would be bought fair and square by primary residents.

Home prices would be lower if landlords weren't hoarding them, and 3% + PMI would be lower as a result. It's simple supply and demand, most kids learn about that in Jr. High School. And when certain people hoard supply, there is less supply to meet the demand, therefore higher prices on the demand side. They are sucking value out of society and not giving back or doing an hour of fair work. Providing housing for over-inflated prices without giving equity is not giving back, it's just taking. When landlords talk high and mightily about charging "fair rent prices," that's code for "as much as the market will let me exploit them."

It's easy to see everything as fair when you're out of touch on top of an ivory tower.
