"Because he knew how hard it would be to get people to work together to save the species, instead of themselves or their children. Evolution has yet to transcend that simple barrier. We can care deeply, selflessly about those we know. But that empathy rarely extends beyond our line of sight."
Similarly, it is difficult to let people work together to change the world from fiat money's slavery, since their line of sight seldom extends beyond their salary and profit, not even mention fiat monetary system itself
