If you want to stuff 4 people into two bedrooms with no A/C and never take vacations you can do it today in most cities in the US for the wage you'd earn at 1 corporate job. It won't be comfortable, but that isn't new.
If you want the boomer city experience, you need to go pick a city today that compares to a NYC, LA, Miami or SF in the 1960s and 1970s. Nothing like 2022 NYC, LA, Miami or SF existed in the 1960s and 1970s.
As someone who lives in a small town in the middle of nowhere, I'd argue that the well-paid jobs part is our biggest struggle. We might be somewhat unique compared to some other small towns, but we have a lot going on - theater, live music, civic groups, outdoor recreation, surprisingly good restaurants - there's plenty to do here, but there's also no question that our largest growing demographic group is people who made their money elsewhere. As both you and the poster below you comment though - neither the big city nor small towns offer much of a refuge for people these days; our system is squeezing every bit of "value" out of workers, to our detriment
Most of the wage growth in big cities goes straight into landlords' pockets. It's no way to run a civilization.
