If anything, they aren't going up enough. Programer's salaries as a whole have stayed nearly even since 1992 [1]. Furthermore, profit margins in the technology sector are remarkably high with very little spent on HR compared to another highly profitable sector: banking. Highly skilled STEM graduates frequently choose to go into finance because they can make more over a longer career without a cap on their income. The ratio of revenue to HR costs at tech companies and finance companies is way out of whack.
If tech wants the best workers, there are plenty of willing and capable Americans ready to pick up the work. Just fucking pay for it. Stop lying through your teeth that this is about talent. It isn't. It's about your stockholders. That's why you only hear the most powerful bitching about it since they are the only ones who would benefit.
