I guess what I'm saying is that a) job market is only one factor in deciding on where to live. A partners job situation, access to other things in life, being close to family etc often weighs in, and is often even more important than other factors. Obviously after such a choice one shouldn't be whining about limited job market - but the point is that only improving things by leaving bad companies is not always the solution. For many it's important to be able to change bad culture as well.
aspect b) is that company environments change, and the fun startup can become a terrible enterprise in a decade.
I wouldn't advise against working in tech in small towns because of the risk of getting stuck in the only gig in town. I would however advise that it be factored into that career decision. One might need to fight to improve company culture, whereas in Silicon Valley one would instead take a job across the street. I'd also recommend keeping an active contact network and online profile so you can get remote work should it be necessary.
