There's a huge gap between "I can't afford to buy a $700,000 house" and "I live on the streets" though. Renting is an option, renting (or buying) and having room mates is an option. Not living in Beverly Hills is an option etc.

I disagree - people generally go towards where the money is. People want to be a hair stylist in LA instead of North Dakota because of the high population density and general wealthiness of the population. During covid, we saw an exodus of people out of the HCoL areas *because* the "non essential" jobs they relied on also moved out (not clear which came first, but the point remains). So generally yeah, if you can't get your hair cut in LA because all the stylists moved out of the city, you'll either commute, or move where everyone else did (which I guess is gentrification in a nutshell)
Either way. I don't think the author is talking about the average starbucks employee here
