Oh, you forget - we lie about social status. Women and men. And as for what determines status ... first rule of social interaction: you can't ask a woman her age and you can't ask a man his wage. (in other words: humans are social animals and "critical" information is only available through playing the social game of deception)

So in practice 80% or so of the population is below "average social status". People who don't absolutely need to pair up, will refuse to pair up with someone below their signaled social status.

In a "natural" human society, it's basically impossible for anyone over 25 or so to "pair up", unless they have a partner, which is not common at all. Since social status ALSO determines the distribution of food, at that point the first real period of weakness (you get sick, you hurt your leg, you ...) is the end. You can delay this by forming cliques, but not by that much.

Oh and of course, that has an analog in our society. Look how much a plumber gets paid (ie. it's pretty disappointing), despite the shortage. There are low status and high status jobs, and even where it doesn't make sense they determine pay. E.g. there are a lot of cities with a total glut of lawyers ... it makes no sense to give 7 figure wages for people when 70% of whom can't find work. By contrast there is an incredible shortage of construction workers, and still they're not paid half of a lawyer.

In other words: I will kill myself rather than admit I'm low social status, even if it would pay well.

Preventing obvious human habits from destroying us seems to me the best reason to really give developing AI your best effort.
