alt Hacker NewsThe only countervailing forces are:
* landlords not wanting as much money (unlikely, although it happens at small scales)
* rent control-type policies
* competition
And as far as I know competition is the only thing that works at scale. Although, people tend to emphasize intralocal competition as where this gets fixed. But I tend to think that the even larger issue is that so many places suck to live in (due to schools, jobs, culture, lack of prosocial governance...) that everyone with options congregates in the good ones.
There's an effect every larger than all of those, though, which is wealth disparity. If incomes differ by fewer orders of magnitude then prices can't vary as much across markets. At the end of the day when rich people can and do buy 2-5 homes and everyone else can barely buy one of course you're going to have problems.
We had two types of competition in the past that are much less common now:
- competition from new builds
- competition from different locations
The first was killed by restrictive zoning. The second still exists but is no longer useful. You can move to West Virginia for cheap rent, but you'll have to move to a location without jobs.
The combination of far less people moving across states and of jobs concentrating in expensive places to live is what killed that second type of competition.
