Rent control will be coming to every state. Even small towns are seeing house prices and most importantly rent going through the roof. No cities are immune.
I would also bet new type housing will be coming out similar to the tiny house revolution. You'll see tiny apartments and tiny hotels like they have in Japan. Just large enough to live in. Something has to give because families with children are the ones at most risk of having to sleep on the street.
No, rent control may be coming to commie states, but not most.
As a landlord of 25 years, I can assure you that limiting our income only limits our ability to maintain and upgrade our rental units and properties. When government is able to control what somebody wants for their product or services, then it's only a matter of time before government controls the price of more and more products and services.
We landlords have no social obligation. I don't owe anybody affordable rent simply because of what they can or cannot afford. I have product and service, I am asking X for my product and services, and you have the option to accept or decline my offer. It's just like taking a job for minimum wage.
If you don't like what landlords are charging for rent, then by your own Fn house.
