Other reasons for darker-skinned people to have lower incomes:
1) Culture does not encourage higher education.
2) Living in insulated communities.
3) Avoidance of integration.
4) Self segregation for religious reasons.
5) Lack of English language skills.
6) Cultural emphasis on non-intellectual forms of employment.
7) Arranged marriage.
8) Residency in poorer States.
Well done.
You left out that many hate whites, choose drugs, choose violence, choose to have sex with a lot of people and choose to have babies without regard for marriage or a serious commitment, choose to rape, choose to rob and choose to kill. Choose the welfare route that democrats have given them in response for their vote, choose to follow people like Jesse Jackson and persecute the cops anytime they get hard on crime, they support the ACLU, they demand reparations rather than work, won't take jobs that are ladder jobs, etc., etc.
