This "too big to fail" argument is BS - they are failing and once cities start to go into death spirals they can accelerate in astonishing ways.
And just to make things extra spicy, thanks to COVID job mobility has never been greater. This isn't your fathers economy. Any of these cities taking anyone for granted do so at their own peril. San Francisco's insane policy of supporting shoplifting up to $900 has caused Wallgreens to pull out entirely, Target closes at 6PM now - what do small businesses do where their only locations are in areas afflicted with these sane policies? When losses exceed revenue they go out of business. As if COVID wasn't bad enough :p
