Unfortunately a healthy housing market is surprisingly a good thing. It's like when house prices collapse it's actually a bad thing because the reason that happened is worse than the result on the house prices (e.g. 2008). People look at the system far to simply, do not understand it and make the wrong judgements. It's the problem of a little bit of knowledge being a dangerous thing.

Many many people have talked about the issues of price caps. It's been done to death. Go look up a podcast, YouTube video, book, seminar, webpage of your choosing and find out why rent caps are bad. They will do a better job of explaining it than me and you can consume the information in the way you want.
Personally I would like some big changes to be made. Easiest of which would be a land value tax which would increase homes and decrease prices. Or much more radical things like destroying parts of cities. Unfortunately I don't make those choices. So reading the information here is showing the opposite of what you think it does and in the system being used is good news.
