There has always existed, since we lived in tribes as hunter gatherers, the potential to put on blinders and not see, understand or recognize the validity of other tribes, even (in the case of racism) not viewing them as human beings.
”...TRIBALISM IN THE AGE OF TRUMP.” is the subject of an article by George Packer in the October 12, 2018 issue of The New Yorker. I quote the whole first paragraph:
“We live in a time of tribes. Not of ideologies, parties, groups, or beliefs—these don’t convey the same impregnability of political fortifications, or the yawning chasms between them. American politics today requires a word as primal as “tribe” to get at the blind allegiances and huge passions of partisan affiliation. Tribes demand loyalty, and in return they confer the security of belonging. They’re badges of identity, not of thought. In a way, they make thinking unnecessary, because they do it for you, and may punish you if you try to do it for yourself. To get along without a tribe makes you a fool. To give an inch to the other tribe makes you a sucker.”
This leads to qualities of human nature I have only recently realized were the driving force for warming. I also realized that these qualities, because they are so common were likely genetic, a variation on how we behaved as hunter-gatherers and perhaps even further back in our evolution. The are several reasons we are in trouble, all as a result of our hunter-gatherer heritage.
1. Hunter gatherers could not comprehend the time scales and distances we deal with.
2. Hunter likely stayed isolated from nearby tribes, just as hedgefund managers have little contact with lower class people.
3. The free-market capitalistic system is inherently unjust. Although millions of people work to support the large companies that earn the billions. These “worker-bees” have been stripped of the power by union busting, but I think most of all by the hideous ideology of low taxes and small government. On th surface this can appeal to almost anyone, but the low taxes combined with numberable tax avoindence techniques have brough the CEO scale to a ridiculous multiple of the minimu wage which has not been increased since it was instituted and is about 1/3 of what it should be.
