I'd say it's a pretty rare luxury to be able to commute less than 20 mins for your entire career. There are tons of jobs that happen in major cities that don't pay enough to live within 20 minutes. Many don't pay enough to reasonably commute by car.

Plus there are a lot of life circumstances that make people accept different tradeoffs over time (schools/districts, medical care, aging/ailing relatives, space vs price, urban vs natural, car vs transit etc).
