Someone explained it with science:

The administrator, the boss, the authority position releases dopamine when they "execute" their authority, so that the boss won't get his dopamine and serotonin feel-good that literally drives all behavior, from their peers, from their fellow men, and instead they derive a higher more potent "high" from exerting power and control through their positions of authority. The only problem is when these positions of authority are REWARDED and their behavior is EXCUSED. This post is excursive of bad behaviors with "everyone is shit". That kind of mentality is undermining to the majority, or the reality of the poor, the destitute, which, very much like the studies show, dependent on the community and on people-skills, where-as the rich are very independent in both thought and act, yet their people skills aren't lacking but arguably inverse, where they don't feel guilt for wrong acts and are much more dependent on manipulation/dishonesty.

If the positions of power carry individual responsibility, so that the person in charge is liable for all acts by eliminating the chance for collusion then power corrupts won't be a rule, but an exception.

The people are given immunity and they rule with impunity, the safeguards for collusion are ineffective at best since these people are by default forever innocent. This is effectively so because the population perceives them as such but in reality they are both liable and very much without innocence, even though they are told "checks and balances".

There is only one law, the singular rule that everything respects, mankind included, the golden rule. The impunity comes with the safeguard born from a long series of fraud and theft and amassing to the largest conspiracy against mankind, effectively not just "legally" enslaving us. The people that act as such do so because they are legally (military) immune, and because they inherently benefit from this slavery. If you look at where this slavery is most complete, I hardly find a case for "people are shit". There's exceptions like most things but the rule is by far "golden" among the most enslaved and "ratchet" is the norm among the power seated. When I see "people are shit" I always have a need to shout "FUCK NO", which I find the most unapologetic objection to that narrative. If we are the People, then we must to take that position, we are powerful, and we aren't all shit, the perpetrators of this fraud upon the world aren't examples for humanity or people as a whole, people gambling with "financial intelligence" aren't examples of the majority by far, Tolstoy understood this, that's why his greatest work is hardly acknowledged, Awakening.
