The fact that power results in antisocial behavior has been understood for millenia.
Lots of societies have had cultural infrastructure of equality that attempts to mitigate this weakness in our biology and prevent harmful levels of power accumulation. The basque village layouts that Davids Graeber & Wengrove talk about, or the practise of ‘insulting the meat’ of successful hunters.
It’s not a question of “look[ing] like distancing or lack of empathy”, or just “bitching about people in power”.
Scientific studies that look at your brain itself - not your behavior - show that as people get more power the brain’s empathy centers become suppressed and you are chemically less capable of being a good person.
