TL;DR Income equality is being redefined as cost cutting through wage suppression. W. T. F.
If you want to define income inequality as the "problem" of different skills demanding different wage premiums based on demand, then sure... If you want to define it, as it has been in almost every report I've seen on the matter, as the widening gap between the rich and everyone else, then that doesn't help at all, it just exacerbates the problem.
STEM work is still a quick, mostly egalitarian way to allow movement from the lower to middle classes. Defining middle to upper-middle class as high-income earners might technically be accurate, especially with a shrinking middle class, but then making decisions based on them being "high-income" when it's so relatively different than it was in the past seems the exact wrong way to go about things.
