With exceptions, salaries aren't advertised in job openings. However you can look at average software engineering salaries to learn that most salaries are south of 100k, and it seems unlikely that on average higher salaries are getting turned down for much lower ones. Furthermore, specific examples are unnecessary. I originally asked for metric that proved there was a developer shortage, and explained why job openings are a bad indication of one. There have been none other proposed to my knowledge, so you're really just nitpicking details irrelevant to my original point.
