That's not what the doomsayers were predicting. They were expecting a detroit-style implosion since the 1970s, suggesting such an event was just a year or two around the corner.... for the last 45 years. Much different than "This city's influence will wane as other metros rise and grow"

Incidentally, Zillow has Chicago and the surrounding metro area posting the highest growth in home value (source: https://www.chicagobusiness.com/residential-real-estate/chic...)

Yet for whatever reason, new expensive skyscrapers keep dotting the Chicago skyline. Some death-spiral.
