This is so obvious to anyone who watches real estate or is in a real estate-related industry. Renewal of a nook of a city due to capital improvements helps- not hurts- everyone down the line.
When I was in a planning session, I was taken aback when a person of just these qualifications was nodding her head that new development hurt affordable housing. If this person, who I thought well of, had this view, what was I missing?
A Theory of Baselines
I think what happens is standards are elevated and in that process, those on the lower end of the scale continue to feel left out. Real estate development and change happen slowly, over three, five, and even ten years to transform an area.
In the fifties, skid row was where affordable housing was located. Then the sixties brought about urban renewal, including bulldozing all these decrepit buildings. Without much research, I can guarantee that the housing provided to people today is far better than that in the 50s. Yet it is a far cry from standard mainstream housing.
With all public goods, there must be a baseline to measure progress. Otherwise, those who are not achieving in school or housing or health will always feel worse off than the average. But are they better off than yesteryear?
