And this is exactly why the society should not subsidize rental living in any way and heavily make it a priority to help private people to buy and maintain ONE house for themselves. Just taxing rental predators out of the market would be a good start, there's no need to ban or outlaw anything. Then actions like giving huge tax exemptions for both the seller and buyer if it's between private persons and the buyer is going to live there would actually send the good signal for society.

However, after all tTis whole thing is just another reason to live in rural areas because rental predators are pretty much non-existent. Of course not everyone is so privileged, but those who are should seriously consider leaving cities for their own good.
