The above link shows various polls, many of them recent, on perceptions about race and ethnicity in America by whites, blacks and Hispanics. Although there appears to be agreement in many cases by whites and blacks about reasons for social problems within the black community - several cited were problems such as single teen motherhood, drugs and alcoholism, lack of moral values - there was a wider gap in the perception of white racism present in American society, and what to do as far as helping to narrow the income gap between minorities and whites.
The history of black people in American society is so very unique, in that blacks were brought to this country as slaves. Slavery and racism as an institution was in existence for about two hundred years and had a profound affect in shaping black people's cultural and economic history, and white people's relationships with black people. After slavery ended almost 150 years ago, Jim Crow laws and racism continued to shape relations between whites and blacks, up until the beginning of the civil rights movement 40-50 years ago. Although slowly changing in make-up, there is still a signficant division in terms of social ties between whites and blacks. How many blacks and whites are neighbors, are friends, are related to one another, worship together? The only thing that will change that, hopefully, will be increased rates of intermarriage. Until then, social separation will continue to maintain the gap all the way around.
