I mean, let's take a hypothetical world - only one person knows how to program. You could say "there's no such thing as a labor shortage - just a price mismatch, she should be receiving one billion dollars for every line of code". But you could also say "maybe we should teach a few more people programming. And clearly, lots of software wouldn't get written, because its cost would be too high.

This is the "same" situation, only a bit more spread out. Maybe those 10k jobs legitimately aren't worth paying more for - that doesn't mean that, if there were more programmers and therefore their salaries would be lower, that software wouldn't be valuable. It's still a good indication that there's lots more to do.
