say someone wants to use IUI+sperm donor in order to buy IQ points (previously: https://schelling.pt/@TetraspaceGrouping/106863321864842499). Maybe they can reliably find a sperm donor with 130IQ, and they have 110IQ; that's +20 difference, half because one parent, half because not heritable, +5 points in child.

1 IQ point is worth $400/y in extra income, so this gives $2k/y total, so NPV at 4% discount is $20k, less than the $20k-40k of IUI, so actually it's not really worth it, and that's why no Repository for Germinal Choice.

Unless they're patient, or value IQ points more, or there are other benefits to choosing sperm donor like attractiveness and athleticism and personality traits. Still, probably better to iodize the salt and remove the lead from paint first.

(replace "is worth" -> "gets you"; I didn't convert benefits that weren't average increase in income to $ amounts)
