This is not a constructive response to an article based on aggregate national statistics. If the article seems wrong to you, at least ask about statistics that might refute it. For bonus points, find those statistics yourself.
Personally I live in a very high rent area (Berkeley), all the houses anywhere near me cost more than $1 Million, but I believe the statistics. To quickly check you can look at rents and house prices in Fresno CA, Mobile AL, Duluth MI, St. Louis MO, Austin TX, etc. etc. The internet has a wonderful set of resources to help us get out of our bubble.
If you want to argue that rents in the Bay Area should be more like those in St Louis, fine! That is a policy question we can work on, but it will be a long slog to get where you want to go.
