Sapolsky’s observation is that human beings engage evolutionary stress hormones in response to purely psychological stimuli. Looking at babboons, who cause each other stress as we do, he finds that lower ranked (submissive) males carry higher amounts of epinephrine (adrenalin) and glucocorticoids than dominant alpha males. (No reports in this documentary on fat-shaming or that ugly females have higher stress.)
So that may be a basis for thinking that social inequality—where a rank and a distance exist—really does mean a lower quality of life for the bottom-rungers, even if they have an absolutely high standard of living. (Sapolsky remarks that in the park he visits, food is so plentiful for the babboons that they only need to work 3 hours a day to survive. So they could be said to have an absolutely high wealth.)
Of course the “right” use of Pareto optimality always took into account the possibility that giving more money to Bill Gates could make me more miserable—but utility is so hard to pin down that a social-optimality conversation can easily be turned by “Well, it’s wrong of you to envy the rich” — casting aside the normative/descriptive distinction.
My first thoughts leap to envy-free solutions of pie-splitting problems (S J Bram, P C Fischburn)
but maybe there are some free-lunch alternatives as well. Such as, is there something I’m doing that makes other people feel ashamed or stressed? Some subtle pitches to my voice or subtle movements of my eyes when I’m internally judging someone but trying to not say anything out loud? Why do I care anyway if some hippie wants to be an organic farmer and not get a job? I don’t think I even have a good reason to care; “ideological opposition”. Maybe you can make some arguments sometimes that I should be stressed about the possibility that my government gets overrun by a bunch of irresponsible ideologues and it’s worth the time to debate about it. Fine, but still maybe there are some free lunches in just not socially shaming other people. Just because I have more money doesn’t mean I need to look down on you as less a person. There certainly are narratives that tell that story—"Contribution to society" type narratives or "Hard work" narratives and sometimes even “Smart” narratives. But I don’t need to embrace those, especially if it’s suboptimal.
Minute 28 they show pictures of monkey brains lighting up in the pleasure centre or stress zones.
Making me think again of taking an integral of the chemical flows over someone’s life (how to deal with time I don’t know) as some kind of selfish evaluation of the pain/pleasure experienced over the lifetime. The naïvest thing would be to measure dopamine and integrate it up over time, perhaps convolved with a risk preference function, anti-variance or pro-variance preference, and some time preference (either NPV/Ramsey or work hard in youth for a delightful old age). Something more realistic would have to take into account that a full life should experience a variety of emotions and corresponding chemical combinations. When your father dies you don’t want to go on smiling and partying, for example.
Minute 48 we get Sapolsky’s interpretation: rank isn’t necessarily it, but rather what rank means in your culture. And our own psychological freedom to decide which hierarchy we think is important. Maybe, RS. Just because I have free will doesn’t make me Herculean, it depends how hard it is to override the bad thoughts with self-affirming thoughts.
Giving rather than receiving. Ask a middle-class parent if s/he is looking forward more to giving something to their child or receiving a present from a friend, partner, or coworker this Christmas? Yet the economics 101 just takes consumption and leisure as life’s desiderata.
So put this together with Daniel Kahneman's supposed finding of an “enough” level (around $45k for Americans I think) above which extra income doesn’t add very much to one’s sense of well-being.
That is, above $45k suponemos que income sea more of a ranking tool or a “You did right” reward. People’s happiness se determine más por the way coworkers and people around them act toward them [do I have to deal with this stressful person today? Does Mr Z laugh at my jokes? Do people look and speak to me as if I’m respectable, smart, admirable, good-looking, sexy, competent, fun, nice—what kind of person am I? Am I good?
] y menos por consumption por sí. Their home is comfortable enough, their food is good enough, life is easy enough. Money removes discomfort rather than providing happiness, kind of idea.
