The list of horrible consequences is too long, I prefer to go directly to the causes; the rules of the game, natural laws in the first place, and generally accepted political rules.
Regarding natural laws, I do not believe that there is any god to claim, nor am I able to imagine a universe with different laws, for good to exist, evil must exist, but immoral traits seem to have an advantage in the fight for survival, the same happens in the struggle for political power. I want to think that humanity is a link in evolution and that there will be something much better for other more advanced life forms.
Regarding the generally accepted political rules, almost everyone sees it as normal that they have to choose between two or three predetermined packs of ideas, accept the centralization of power and impose their will on the rest of the people through the vote, they do not realize that by stopping the ideas of others franan their own ideas (those who have), society could organize itself in many different ways and experiment without imposing.
