We have an expression here: "the tallest wheat gets cut first". It's normal that people who succeed expose themselves to criticism, it might be harder for people of a 'poor' minority to accept because not only will they be moving social 'class' their circle of 'friends' will change colour. Understandable that they sometimes question if they are true to their roots. Understandable, though perhaps unforgivable, is that they are accused by others of betraying those roots.

Perhaps it's still a bit of African culture that has remained, success should be shared with the tribe, and not kept for the individual, perhaps this view (subconsciously) persist in black America ? Still, roots are important, consider all those threads here asking people for their ethnicity. many Americans seem to still consider themselves italian, Irish or whatever other country their ancestors lived in. Blacks, certainly those descendant from slaves can hardily do that, their culture is purely American, black American even.

I wouldn't change this in a partisan issue though. Sure the democrats might appeal more to black America, but that's probably because they are a 'city' party far more than the republicans. More black people in the cities, ergo the Democrats should appeal to them more, simply since they are part of the main target group.

Honestly the only thing that will ever solve this imo is mass interracial breeding. It's time we get over this whole 'race' thing and move on.
