I wouldn’t expect anyone to deny the existence of corruption or abuse of power, but I think the corrupting influence of power is often used to justify in retrospect the acts of people put into power to do exactly that. It might sound pedantic to say that CEOs or state officials aren’t really “corrupt”, because they rarely ever intend to represent the interests of the workforce or population, but really it’s a total inversion of causality. They don’t “betray” because they got in power, they got in power to “betray”.
On an interesting sidenote, it also goes against the common misconception that any form of authority ultimately leads to corruption, since those same CEOs and officials seem to stay pretty loyal.
Our economy is organized around exploitation, I understand the point that someone in power might use this power for their own good if unchecked, but in an economy of exploitation like ours, power is organized around said exploitation. The worst of people go to the top not because bad people inherently do (or as you say, because power incentivizes bad action) but because this system is structured around exploitation, being ruthless and clamping down as hard as possible on those below you.
I don’t believe that power generally incentivizes bad action. Outside of the structure of a company or a capitalist state, it’s merely a factor to account for, like any other conflict or human element (and is usually handled fairly expeditiously). In my experience in non profit organizations, usual “human issues” are of course presents, but corruption and power abuse only ever rear their heads when the rubber hit the profit road.
This confusion also isn’t a mistake, it’s a misdirection, perpetually maintained to depict the constant corruption of states and companies worldwide as a mere “unfortunate reality” of human organization, while minimizing scrutiny of the structures this corruption exists in. When Trump, Elon and friends are waging a crusade against corruption, you would think this misdirection is at its absolute stretching limit, but somehow it still holds strong even (and especially) in those critical of them.
Sorry for stupidly long reply, in a word, I think we shouldn’t mistake “profit incentive”, for “power incentive”.
