A city can't function solely with high wage, white collar professionals, and there's a practical limit to how far low and middle wage workers can commute from cheaper exurbs.

We're seeing the cracks starting to form now. It's getting harder and harder to find city workers to take jobs that historically have been pretty desirable, even if they only offered modest wages in return for stability and great benefits. Bus and train drivers, teachers, nurses, etc are necessary to make the city run, but don't offer the high salaries that are increasingly necessary to afford living within or reasonably near the city. A complete drain of vital workers as cost of living continues to rapidly outpace wage growth.

We're facing an exodus of working class people from exactly the places where they are needed. These high cost of living hubs will be the homes of the very wealthy and the desperately poor and few in between. A city full of elites but no teachers or garbage collectors because they can only afford to live 2 hrs away.

High cost homes and tent cities surrounded by massive congestion as the people who help make the city run languish in long, miserable commutes.

Hope the NIMBYs enjoy the neighborhood character they fought so hard to preserve. It'll sorta still be there as long as they avert their eyes from the nightmare of extreme poverty and homelessness they are creating.

The same applies in expensive vacation spots like the Cape or the Berkshires. People buying or renting expensive houses only to find that there's no waiters at the restaurants or all the other service jobs that don't pay the high salaries required to live there.
