If it was easy to produce smart kids then we would already do it, since smart people are so much more valuable to society the small amounts it requires to add that extra value would be nothing. But no country has managed to do this so far, its just a slow climb that follows the same trend in every western society no matter what policies they implemented.
This goes against all of the scientific literature we have. Intelligence is determined by genetics. It can be artificially lowered via poor socio-economic conditions, but it mostly cannot be lifted by higher socio economic conditions. In laymans terms, a traumatic life can make a child who was otherwise going to be smart not so smart, but a good life cannot make a child who was going to be dumb intelligent. Socioeconomic conditions can lower the intelligence determined by genetics, they cannot improve intelligence determined by genetics.
Have you considered it’s because being a poor child is itself a traumatic experience that isn’t magically cured by being ripped away from family and put into an environment of material abundance?
What you've said is unfalsifiable voodoo mumbo-jumbo. Even if someone proved you wrong here and started the experiment with the poor child at newborn level, which is what people do when these bad faith criticisms are lobbed, you'd just claim that the DNA of the baby inherited generational trauma, which is what people with your bad faith criticism resort to once the criticism is inevitably proven wrong.
Doesn’t really work like that. IQ is heavily influenced by environmental factors.
Unfortunately, most smart and educated people are actually doing the opposite. That is, not having kids.
