Maybe we should build lots of housing around (at least some of) the areas where economic opportunity is concentrated. Many US cities exist as they are today due to people looking for economic opportunities in the past (for example Chicago grew from 299,000 to around 1.7 million in a 30 year period). These days it seems like non-professionals are priced out of all the most booming cities (despite there being plenty of non-professional work available). I don't think it's a coincidence that it's currently very difficult to get permission to build in many of those places (in 2014 Tokyo permitted 70% more housing units than all of California, despite having 1/3 the population). The under-supply of housing in places California of course increases the demand elsewhere too since those people that would otherwise live in California have to live somewhere. Basic income could help mobility too since it makes it easier for lower-income people to move to where the jobs are (where they may not have a family safety net). Currently internal US migration is at a historically low level.
