First, things weren't like this even 10 years ago. Humility in power had long been a fundamental American moral before that: All are created equal, the rejection of aristocracy, and the foundation of freedom and self-determination; freedom of religion and speech - nobody else should tell someone what to say or their religion; George Washington refusing to accept more power or a third term; the humility of leaders like Lincoln and Eisenhower and King; the supremacy of civilians over the military; the early New England culture and Henry David Thoreau; the required public humility of almost every president before Trump - nobody talked or behaved like him. I read a ~10 year old New Yorker article recently about the public humility of many Wall Street leaders in the 1980s, at least, who wore more modest clothes, built their houses with low fences, etc. The pioneers of the Internet who believed in openness and end-user control. I read something old about SV - from the early 2000s I think - a conference of CEOs, etc, and someone asked who flew in their own jet; the speaker remarked how embarassed many were to raise their hands.
The good news is, that moral existed for centuries and is part of the American fabric. We just need to be reminded of who we are and of what really made America great. (Yes, there were endless exceptions to it - in every person is good and bad, pride and humility - but today narcissism is embraced.)

I don't see how those things reconcile. I think people in each group are, on average, just as likely to be corrupted by power, etc.
It's the power that does it; it's the most powerful drug, the Ring - until they have power, you don't know reliably how they will respond. Fewer non-hetero-males and minorities have power, so it may seem like they aren't corrupted by it.
'If you want to see someone's character, don't give them hardship, give them power.' The American elite are failing the country and the world.
