It may be good politics, but I am critical of it. The victims of American racism were individual human beings. AA does not look at the individual and what harm they suffered, but again, only looks at the color of the skin.
The election of Barack Obama was a great victory for the USA, but also an indictment. He was not born into an African American family, deprived by segregation. (The British occupation of Kenya was brutal, particularly during the last stage - the Mau Mau rebellion, with its 10,000s of dead - when his father came to the US. But I don’t know what his family’s role was.)
All over the world, we can see that having less educated parents is a burden for the academic success of children. This is completely unrelated to racism. Less educated parents can’t help with homework as much, or impart academic knowledge in passing. I can’t even imagine what it is like, on top, to have parents/grandparents who have only ever known a good education as something that gets you murdered by white people.
Obama did not have all that ancestral baggage, and he had this brilliant career. That’s common for recent African immigrants.
Maybe AA helps the US become a better, stronger nation. But I worry that it may perpetuate damage by still practicing differential treatment, based on assigned racial category. In any case, it does nothing to redress the concrete harm, done to individual human beings.
