Cynically Maxine Waters seemed to be engaged in sociopathic manipulation tactics instead of actually trying to solve anything. It looks like a shakedown. Either they give contributions to shut her up or she gets to try to score points by beating on a boogeyman.

Last I heard the AAAs in the tech were leading the pack in minority hiring of all stripes by sector. If it was mostly company culture to blame one would expect most black workers to be concentrated in small businesses or self owned and operated. Not saying that is a solution for discrimination by any means; self starting isn't easy especially when lacking opportunities but that it is a hint as probably pipeline sourced.
