Your entire post makes the claim that it’s because the vast majority of programmers get paid the same as other roles and that’s why there’s the language selection pressure there is. High salary jobs would be the exception yet they also make pragmatic choices about languages. It’s a two sided market problem - employers want popular languages to be used so they have a talent pool to hire from and don’t end up having a hard time finding talent (which then also implies something about the salary of course but it’s a secondary effect). Employees look to learn languages that are popular and are easy to find employment in. Not sure if you’ve spent any time with them but VCs and investors more broadly generally could give two fucks about the language a business is built in. There are exceptions but generally they just want to see the business opportunity and that you’re the team to go do it. There’s a reason it’s difficult to find employment with Haskell or Lisp or other niche languages and it’s because they’re niche languages that “you have to get” - not easy to learn and generally not as easy to work with as “popular” languages that see significantly more man hours dedicated to building out tooling and libraries. There’s also secondary things like runtime performance which is quite poor for Haskell or Lisp if you’re a beginner and even people familiar with the language can struggle to right equivalent programs that don’t use significantly more memory or CPU. And finally the languages can just be inherently more difficult and alien (Haskell) which attracts a niche and guarantees it remains a niche language that attracts a particular kind of person.
