There are two aspects to this: one is alleged pay discrepancy for different genders in the same job performing the same duties (which yes, I do believe is still an issue), and the other is alleged discrimination in hiring for higher-paid positions (which yes, I do believe is also an issue).
I consider myself to be an "average" person. I was in upper management at a government agency that oversaw a predominately male industry (oilfield). So there are arguable reasons why the regulatory agency would have discrepancies of that sort, I honestly don't think them particularly valid. YMMV.
