But what if you like not being unemployed?

IQ is important, but it's only a means of assessing the G factor. The G factor is highly resilient to environmental change and estimates greater group differences in intelligence than sub-optimally g-loaded IQ tests.

Additionally, the SAT, which isn't even an IQ test but just highly g-loaded and proxies well as an IQ, shows that the poorest Whites still exceed or are the equals of the richest Blacks.

>Achievement varies historically

I'm not going to go into the weeds of arguing over qualitative historical sources, but when technological progress is quantified as best as possible there is remarkably little variance in which nations are the most technologically advanced for their place and time.

As you can see there seems to be some underlying factor which determines national outcomes that remains constant despite environmental and cultural changes. The most obvious explanation for this are genetics.

>Environments (particularly family) determine life outcomes

You're glossing over a very controversial area of psychology with hardly any kind of thorough analysis and instead just offer your opinion. Family does affect IQ, but to begin with smart children will by virtue of their genetic lineage tend to have smart parents and independent of this fact educational attainment and life outcomes have been associated with the genes of your parents qua the genes of your parents. I.e. Genes from your parents explains 50% upwards of educational attainment and your genes explain 80% of variation in IQ which has knock-on effects regarding career and academic performance.
