Absolute power corrupts absolutely.
A lot of people when they are given the chance to have power go crazy. It is just too much for most people. When they get the crazy thinking that they are entitled to this power... Things start to shift and end up extremely badly.
However with so many good community members fighting back... I have a lot of Hope for our blockchain.
I know what you mean - people often have a lot of unrecognised or underaccepted emotional imbalances based in lack of self acceptance that has them constantly trying to 'beat' everyone else in any way possible. This can manifest as exceptionally loud people who never listen to anything but who just keep talking or it can be the powermonger money obsessive on Wall St. - or it can be those who start literal wars, killing millions without a second thought.
Unfortunately, the flipside is that these people can generally only operate because the mass of people has been brainwashed to reject personal power as 'bad' - partially as a result of looking at the powermongers and being fed the idea that if they hold personal power that they will be just as much of a problem for humanity. In both the case of the powermonger and those who abdicate power, it is a lack of self acceptance that is at the root of the dysfunction.
