Those who can will step up to the task. In my area, we already have thriving local producers. We also have scalable grwnges and co-ops. No doubt that hard times are doming. A lot of folks are going to perish of disease and starvation. But not everyone. Those who have skills will do well. We’ll still need teachers, historians and beer brewers. Im all three.
Think Clarksdale, Mississippi, birthplace of the blues. Businesses are on the outskirts of town. Cheaper to develop than refurbish. Perhaps one business open on every block downtown. It’s the chains taking the path of least resistance. All the colorful history. Cottons not the same.
