Glad to see another person who recognizes that, at a basic level, this is something ingrained in our species. I wish I understood where greed originates within our nature and how to eliminate it, but history demonstrates that this has always and will always be part of who we are.
I think Terminator 2 put it best: We're programmed to destroy ourselves.
That said, at least here in my own small sphere, I see some lovely examples of kindness. There's a donut shop nearby that puts all the unsold stuff in a box at the end of the day and leaves it out for the homeless, or really, anyone that walks by and wants to take one.
