Concentration of wealth and power was (and is) the highest in communist dictatorships - literally a handful (i.e. less than 5) people control pretty much everything in Cuba. North Korea is ruled with an iron fist by 1 guy - that is some concentration of power, right? In Communist Romania / East Germany power was concentrated in 2 people (a couple). In USSR power was concentrated in the 7 members of PolitBuro. In China power used to be concentrated in the hands of Mao Zhedong, now it seems it is concentrated in the hands of Xi Ping (but I could be wrong about Xi Ping. Maybe he shares some power with other people). I could go on forever, baby!!!
Capitalism has its problems but capitalism is quite fine all kinds of political systems - see German capitalism before, during, and following Hitler's rule.
Concentrations of power seem bad, regardless of the mechanisms that do the concentrating.
The robots and automations are like the trees and bushes from our gatherer's past.
People would just take what they needed. No one would say: you are not allowed to take a berry from this bush because it's mine!!!
It is insidious how easily we divide ourselves into rival tribes. For too many it's not enough to feel belonging within a group, they/we crave others to look down upon or fight. IMO we are our best when we can debate ideas dispassionately, without defining ourselves by them.
Roger Scruton in I think this video: https://www.youtube.com/watch?v=1eD9RDTl6tM. Says that basically conservatism in the 80's in the UK was whatever Margaret Thatcher believed. This really I think helped me understand why the conservative transition from Reagan/Bush to Trump went more smoothly than I thought it would among trad conservatives.
Tribalism was a key substrate. This often manifested as a near blind loyalty to the party and chosen thought leaders like Bill Graham, Rush Limbaugh, Bill O'Reilly, and now Tucker Carlson. They told us how to interpret events and we repeated the talking points. They gave us the (often contradictory) rules and principles we were to use to view everything in life.
It suggests to me, having encountered it for the first time, that programs must be readable to remain useful. Otherwise they'll be increasingly difficult to execute.
