@Cyracuz,
Humans would fight over pretty silver paper if given the opportunity. It seems that a good deal of the "survival" instinct takes the form of accumulating.
We have plenty in the US right now...lots of food, water, shirts, pants, televisions, water heaters, lots of doctors, nurses, and places where hospitals could go; cars; schools, teachers...and we could have as many more (much more) of any of those things with relatively little effort.
We could easily have abundance...and we do.
But the winners of the survival of the fittest always seem to want to corner the market...to hoard.
There are people with no place to live...and we have rich people who have huge homes in dozens of states. We have people who do not have nearly enough to eat...and we have others who throw food away.
What the successful want is what Oliver wanted: MORE!
MY GUESS: We'll never get past that. It is what humans do.
