Black ppl definitely should. Infiltrate and bring back resources.
They just have to move quietly.
It doesnt work. Even DuBois wrote about this phenomenon after he personally lifted up black people in the 20s, 30s, and 40s. Without failure, they all lost motive to help people in the struggle immediately after they themselves left the struggle. It boggled him at the time, but the same pattern has played out for decades.
I argue that most black people are insincere about caring about other black people, and only appear to do so because their present existence depends on it. Take away the eminent threat, and their love for other black folk whithers on the vine. I dont even think this phenomenon is unique to black people, because even among whites; those who care most about racial identity are the least established of their group. Think of how wealthy white republicans would gladly replace their poor countrymen with hispanics. Or how wealthy white democrats would do the same with indians or Chinese in tech. Or how the industrialist Carnegie, a formerly poor white man, gladly replaced whites in his factories with black people in the 1890s and 1910s.
Personally, I think you need a better motive for black folk in high places to help other black people. Something as simple as making it profitable for them to aid normal black people might be a good start. But anything resembling obligation, retribution, or "warm fuzzy feelings" aint gonna work.
