In short, did fear and greed level change?
Yes, I would say that people have became less agressive overall and more friendly to eachother over the longterm.
Slavery was abolished, racism is diminishing, and humans have just a better social intereaction. Also couple that with social media and a reputation system, you can pretty much find the bad apples very fast.
People cannot become too greedy without a societal backlash.
Corporations on the other hand are protected by the government, and are given taxpayer bailouts.
It doesnt mean that the population doesn't want to hold them accountable, its the government that doesnt want that.
