There is a finite supply of STEM minded people, the extreme salaries in programming has already shifted many of those to programming. The job climate today is basically the same as 10 years ago, the interviews looks the same, the salaries are a bit higher but around the same etc. So as far as I know this is the stable point where the people staying in other STEM jobs prefer those jobs over the money, and you wont attract more of those unless you pay even more than companies do now.
