I also think anger is more psychological than real (because anger comes from within). Contentment over time seems to be based in the share of the pie rather the size of the slice. Anger seems most concentrated among low-educated White men. They are not living any worse than in the past but their status has eroded as our national attention has turned to other issues. Immigration used to bring new entrants who had to work their way up over a couple genererations. Now, new immigrants can leapfrog over the natives in a few years.
But ever the working class live better than they used to. The pickup trucks they drive are pretty luxurious compared the old ones of the 1970s.
If anger is psychologically self-induced, it can also be self-healed if one takes time to self reflect.[/quote]
I totally agree about anger and the psychological underpinnings, The same thing could be said for hubris. It has been said that anger is a form if temporary insanity. Maybe hubris is similar in some ways even if it is more sociable.
