Hardly. This is actually kind of insanely tone-deaf statement to make. People have uprooted their lives, spent lots of their wealth in expensive real-estate markets due to artificial demand, given up time with their families, etc etc.
Saying it's "worked out" is a really bland dismissal of the entire conversation.
Doctors are somewhat unique in the fact that they can live and practice in a wide variety of places. Anywhere there’s a hospital, you will have them. Where they will choose to work/for how much is a much wider decision matrix than it is for many white collar organizations which would have no reason to exist (physically) in a small town of 20,000 people. Such a town would require at least a single hospital employing many medical professionals, depending on how far it is from other forms of medical care.
Doctors are just one example and there are many reasons why a doctor may choose to practice in, say, the Boston area than in some 20,000 person town in North Dakota--though you're right than, in many cases, medical professionals have a pretty wide choice in where they live and work depending upon how choosy they are.
But a ton of STEM jobs do require access to labs and other facilities or may have requirements related to security clearances etc. A lot of skilled people can't just work from home and many others travel a lot even if they don't regularly come into an office.
In the context of the modern American nuclear family, the concept of both adults working is relatively new. The traditional arrangement was one breadwinner, one homemaker, and ~2.5 kids.
Which is still common these days, but not to the point of exclusivity: I work remotely, but my partner works hybrid.
There are tradeoffs, sure. But there are a lot of jobs in a lot of fields in a lot of places.
The venn overlap is not tiny.
