They exist by manipulating white people to take care of them. If they appeared to be happy, that would dry up the free hand outs from white people. Therefore, they must continuously portray themselves as victims and blame all their problems on the racism of white people. Ironically, even millionaire nigger entertainers and athletes think this way.
As a whole, niggers are unable to properly care for themselves or manipulate their environment to better themselves. This is best evidenced by their squalid living conditions in Africa where they have lived a stone age existence for thousands of years. The only reason they enjoy modern luxuries is because of the generosity of white people.
