If one's primary objective is to maximize income/money/wealth, then you should be prepared to be more flexible with the kind of work you do. There are many careers that pay more than my chosen career, but I am not interested in that work. Hell, it even applies within an industry. There are some companies in tech that have to pay a lot more to attract talent than other companies, because of their reputation, their culture, etc. You can choose to work there to make more money but it does not mean that other companies with better working conditions and more appealing products etc. should automatically match comp. Put differently, there can be many reasons why people choose one job, or career, over another.

It is unreasonable to lament that your chosen work does not pay as much as another job, and more unreasonable to expect all jobs to pay similarly.
