It does not seem likely to me that a multimillionaire would prefer socializing with a poor person of the same skin colour over socializing with another multimillionaire who happens to be black. Ah, but it's the other side of the socioeconomic coin that's key; southern plutocrats blunted the sharp tip of progressive unionization by convincing poor white sharecroppers and field hands that they had more in common with the wealthy white landowners than their fellow black workers. Similar political strategies dominate today -- some race-based (and sharper than ever!), some on other social issues.
