How private equity is changing housing

I just watched a video from Dave Ramsey title "What the Government Should Do to Fix the Housing Problem" He specifically calls out Institutional Investors and Foreign Corporations that have been purchasing single family housing and converting them into rental properties. I think he makes some good point in his video: https://youtu.be/_CrgniwSLLM

Why do you think that renters don't deserve to live in single-family homes?

Not at all what the GP said.

They aren't saying landlords are the problem, they are saying Institutional Investors and Foreign Corporations being landlords are the problem.

There is absolutely nothing wrong with institutional investors buying tract homes and renting them out. Nothing! It brings the benefits of living in such homes to people who otherwise would be excluded from them by the financial credit system.

Well really I was just trying to explain the GP's post, not adopt their views, but I think I can play devil's advocate here for the sake of discussion.

The problem with institutional investors is that in making it big business you drive up home prices which in turn drives up the rental prices. Since they can have a wide portfolio of homes, they are less likely to lower rent prices when demand drops, because they can afford to take the short term hit if it they think the market is going to pick back up again. AND they can play games like grabbing all available homes in an area in order to artificially inflate prices.
