Nice parable. There will always be selfish people.I remember a long time ago, in the early 90s, my family brought in woman and her two children who grew up in East Berlin (they traveled with my Uncle, who's from West Berlin at the time) and we thought how amazed they would be if they saw "Old Country Buffet" - a place where you can have unlimited food to your individual desire, as opposed to the minimalist rationing of food that they were used to. We thought we were showing them heaven on earth!
They weren't amazed. Instead, they were absolutely revolted and horrified by it. They stood dumbfounded, wondering why people were gorging themselves so much - and why there were so many options. They each had a small salad and that was it.
I also remember a time when I was talking to a friend of mine saying how interesting that there are so many men running cooking shows, and he turned to me saying "It's only natural that men like to cook, as men like to tinker and create things"... I began laughing at him, stating how not 50 years ago all men thought the kitchen was a "woman's place" and if he suggested that - he would've been laughed out of the room.
Finally, I remember a piece where John Oliver was interviewing Australian Governors about policy, and asked them what they thought was the mark of a good governor. They responded "If they publish good policy that helps the people", when he asked an American governor, he responded "If they get re-elected."
My point here is this: To say that they're "a part of humanity" is wrong - it's more accurate to say that they're "a part people in our capitalistic culture". That is something that can change. Please don't equate your own unchecked greed as something completely natural. It's really not. Even Velociraptors, one of the most terrifying of Dinosaurs, understood the concept of working together. That's what made them so terrifying, actually...
