In what way does this graph say humans are not corrupt and taking advantage?
Even under communism the 1% had 4% of assets, that's not 1% of assets like true communism should be. That in and of itself proves corruption to me. The fact that the USSR fell and a handful of 1%ers got the majority of industries for pennies on the dollar is egregious corruption. None of this is a criticism of communism. This is criticizing the actions of individuals who decided to be corrupt.
It's just human nature. Some people call it "enlightened self interest" others call it nepotism, some call it survival of the fittest. Some call it gaming the system. In all cases it's the same problem. Sometimes things can go well for a while but on a scale of even just a hundred years when an organization has more than a couple hundred people it simply goes sideways.
Getting everyone to be involved and knowledgeable about absolutely everything and to fight to make things right is beyond the capabilities of current humans. The more I know the more I understand I don't know a lot about so many things beyond what i've experienced. Ignorance drives so many reactions (including the personal attacks from my comments here.)
I have met many individuals in this world who get very, very angry that someone else is doing x, y, or z - even if it has zero impact on them. Some of the reactions to my comments here about a very logical challenge that could have solutions with technology are attacked with illogical non-arguments and are a perfect example of how impossible it is to get humans to think critically about things when they have their own biases.
