As a transgirl, WHO IS ALSO A WHITE SUPREMACIST, let me school you, Boy!
The mating game is kind of whatever. White people are losing the "mating game", as in child birth, strictly because of our high IQ, unfathomable to nigger and spic hordes. High IQ rich white people would rather have one child, and spend 500k on it, where as low IQ nigger hordes will have 2 children and let it live in it's own shit and piss, lol.
Also who told you IQ is an outdated measure of intellect? There isn't any data to back that....
IQ correlates about .5-.6 with education attainment and occupational status. Even, IQ at age 18 predicts socioeconomic status in adulthood better than parental background.
Each standard deviation increase boosts earning by 10-20%.
IQs skew above 120-130 for tech and science too.
So yeah, IQ 100% matters. America isn't a tribal society of nigger hunter gatherers, we are a highly technological society, bordering on break away civilization levels. What we need are policies that promote child birth, like what the nazis did where for each child 1/4 of their home debt was alleviated.
