I was just at the newest mall in San Diego, in La Jolla, one of the wealthier areas on the Southern Cali coast, yesterday, millions and millions invested in dining/shopping options, and it's active, day and night, whether people who are shopping or going out for drinks/dinner. I went to my spots, and had lunch at a new Dim Sum place, but what that says is rising inequality. The malls of my childhood, are closer to like a TGI Fridays, the lower/mid end of the economy, but a robust part, now it's not that way, and the high end is continuing, (look at Hudson Yards in NYC for further proof, I was there last month, you can drop $500 in 5 minutes in Niemans, and go have lunch at David Chang's new place in the same 100 feet or so), but the lower class places are dying, rapidly, and are replaced with probably new developments residential and commercial that those of that class can't afford, another former of gentrification. That segment of the economy is now who drives Lyft, Uber, etc etc all the gig economy to just hang on.
