Well that’s just a fucking trip of dysfunction.
Just that bit is a lot.
If the population declined and it makes the economy do less well, won’t people just have more children like they did the last time the economy was in that state? Every environment has a carrying capacity for the creatures that live in it. It’s not uncommon to see fluctuations above and below that equilibrium point.
Instead of pushing people to ignore the factors that cause the limit in humans, like not wanting or needing more children, maybe find a way to organize society so hitting that limit doesn’t cause massive problems, or try to eliminate some of the factors creating the limit. It’s insanely difficult in our society to have even one child who’s healthy, cared for, and prepared for their adult life while also being personally healthy, prepared for old age, and enjoying the variety of pleasures of existence.
You don’t have to go out of your way to defend things that are putting a nice veneer on eugenics.
And for the record, if you read the article it’s clearly about them being arrogant and generally absolutely fucking weird. “If more people like us don’t have children, the world will stop seeing innovation and economic prosperity. It’s very important that the right people reproduce.”
