Massive investments in black communities. Comparing the treatment of the Irish to 400 years of institutionalized chattel slavery is absurd on its face. Also, again, ignoring everything else I mentioned. Some books you should check out to learn more about this. The New Jim Crow and The Color of Money. Black communities have been chronically underfunded, underserved, over-policed, and segregated for the entire history of our country.
Rich African Americans commit crimes at a higher rate than Asians and Whites at the same socioeconomic level.
Irish people haven't had a particularly pleasant past either, and you don't see people making excuses for them.
