Does the book address family structure and welfare incentives?
For Whites or Blacks to match Asian success outcomes, I would focus on the family. Marriage, divorce, and children out of wedlock. Start there. Those are the clearest signals of the values that actually lead to successful outcomes.
Big government could incentivize the hell out of having children inside marriage and support long term marriages at least through the kids school years… the complete opposite of the Man in the House destruction policy that FDR and LBJ pushed.
Reduce the marriage penalties. Make benefits neutral or positive in favor of two parent married homes (or multi-generation family). Stop letting long term welfare compete as a substitute for a husband's income.
This reduces the environments that produce higher crime and reduces the cycle of unstable families.
The destructive loop is anti-family incentives -> poverty -> crime -> lack of education -> unstable family -> anti-family incentives.
Outcomes and behavioral biases are more driven by family environments than skin color.
Rational behaviors toward groups is practical... and natural... (my young children auto insurance costs are high, walking on the other side of the street from white (e.g. any race) teens in hoodies with menacing face expression, dirty grooming, walk, talk, dress, and act like trouble does).
