People have been doing something about it. That’s what all the weird return to office intiatives were about. City governements are scared that the downtowns will spiral into collapse so they coerce all the companies that still have downtown offices to get their employees back and spending money at restaurants and such. If the restaurants go out of business and store fronts sit vacant, then there would be no reason for companies to pay a premium for downtown office space and the whole thing collapses Detroit style. Commercial real estate failed to price in remote work, and the covid shutdowns made it obvious just how overpriced and overleveraged it all was.
