White males are overly represented but I think it's fair. After all the US is white male culture at the higher levels so those who grew up with this culture have an advantage. They are fish while everyone else are forced amphibians. It's natural for advantages to compound.
Change in culture often comes with damage of supplantation of existing cultures. US culture is unique in that is can coexist with other cultures but isn't entirely replaced. At least not the high status portion. The low status portions have been excised. (trump supporters)
To replace high status white male culture there needs to be an equivalent high status opponent. Pao's article I think is useful in that it targets this directly and doesn't just stop at discussions on passing whiteboard interviews for IC2 positions.
It's expected as with any invasion that there is collateral damage. Trump supporters feel impotent and sidelined. These higher level incumbents are a lot more crafty and a lot more powerful. We can't even deal with rascists except defang them and wait for them to die.
This is why high status Chinese/Indian female/male culture doesn't exist in the valley for the most part, at most upper middle culture. There's not enough space at the top and it isn't worth it to start a war. Because in culture wars, home turf always wins. Giving coal power plants unlimited nuclear fuel or tidal plants unlimited sun doesn't tap into the necessary power.
Chinese/Indian high culture taps into society. For people in the valley this source of power is removed. I'd say that US high status white male culture is more standalone and deals with pure power in the ability to manipulate or coerce people. Interestingly this spreads more easily across gender than race though often the new entrants must give up their old culture in many ways.
For males that don't give up their mother culture they can feel marginalized and impotent, feeling that everything is unfair. For those that do they see no imbalance. The gap for women though still exists.
