Many woman of color are simply not entering the pipeline. But those who are there get wildly favorable treatment compared to people from other demographics with similar capabilities.
To put it another way - I have seen a lot of Claudine Gay's at work. Generally smart women, checking all the DEI boxes, given juicy opportunities way beyond their abilities. People from other demographics have to struggle a lot to get such opportunities.
Explain it to me since I've been in the industry for quite some time here and I can't say I've seen what you're hinting at.
