I can speak from my own experience only as I dont study the statistics, but in 20 years of work as a white male I can categorically say ate that my race and gender has never been a hindrance in my career progression. I dont doubt the possibility exists, but I do not based on my network feel its to any noticeable degree. As in, I havent ever observed it happen, as a hiring manager myself or by a hiring manager.

As to your second part, as to what its origin is, its clearly in response to a multigenerational systemic suppression of certain classes. That is not in debate, and frankly from my white male perch, I continue to see firsthand much more of the lingering slights and biases against certain classes and groups, that affect their career and their inclusion, than I ever have any anti white male sentiment or anti white male advancent credo.

So in summary - I really dont think much has changed, and that isnt a good thing.
