>no one is going to commute 90 minutes for a minimum wage job when there are plenty of jobs available elsewhere
A few things:
1. The premise there (when there are plenty of jobs elsewhere) is kinda flimsy -- its already easier to find jobs in larger cities (that's why people move there), and nothing guarantees this won't get worse
2. Yes, there is a breaking point where people can't afford (in terms of time and/or money) a long and/or expensive commute. Humans have a workaround for that. Its called slums.
