Wow, how stupid can one “analysis” be. It does not understand causation vs. association and in one breath talks about concentrations by geography, then on the other completely omits geography from considering average salaries. If only there were time to discuss all the other partial truths and mismatched comparisons.
Gee, if one followed the money, any guesses where this would have gotten its funding? Odds are its someone who directly benefits from what it’s selling.
