re: Crane City - Why is there is Skyscraper boom in most major U.S. cities?

We’re in the early stages of a commercial real estate meltdown. This will be absolutely disastrous for cities as it will collapse the property tax values for all of these mostly vacant towers when they can’t get bank funding.

Plus, due to the major differences in how plumbing is run, it’s extremely expensive to convert office space towers into residential ones.
