It has to do with their racist culture. It's a very sad thing to see that over half of all "african americans" are more racist than the KKK.
This racism makes them close-minded and cling to what they feel "is their culture". Remember the phrase "No snitching"? They build it into their culture. The "Hate Whitey" stuff? same thing.
What's worse is that this ignorance, best seen in Rev. Wright, blinds them from the real solutions to issues - It's not a poor black guy living in a rich white guy's world, it's a poor person living in a rich person's world. Want to fix this? GET AN EDUCATION and get yourself out of the lower class. Nobody's going to do it for you, only yourself.
