The risk of eviction, meanwhile, can be roughly measured by the percentage of people’s incomes that they spend on shelter each month.

Adam Smith observed years ago that cost of housing tends to eat up most people's pay raises. Which is to say if you can afford more you get more. Of course there are limits.

The cost of building, in terms of land, approvals, delays in construction, etc is also not favorable.
At least to me as an outside observer, it seems EXTREMELY LIKELY that the 'market' is misaligned to the needs of the people and in need of a deep systemic overhaul including a review of regulations that encourage / discourage various activities.
