We here seem to be addressing aggregates, not individuals. Now talking about persons, whether it is unfair to put the blame on them in particular for a lacking part of their culture (priority and emphasis on education), I am not sure if they are to be blamed but I am not addressing whether they themselves should be blamed. I am instead addressing that blaming externality for matters in which internality is the overriding and deciding factor, is innacurate. Gangsta rap, that might have gained vigor and strength of influence because of injustices, is not really a factor of that culture that in itself de-establishes the importance of education in that culture. Extarnalities(social injustices) seem to effect for the most part such cultural aspects as harsh feelings, expressed through music, other on the surface charectaristics and external consequences, they hardly penetrate internal core charectaristics of cultures that are already there.
Externalities, if a certain core charecteristic in the culture is there, cannot change that. Meaning that if the importance of education is already there then social injustices will not make those factors of a culture dissipate. There hasn't been relatively as much prioritization on education within the African American, Hispanic, and Native American cultures. That is what we need to change, in conjunction with helping persons from those cultural backgrounds with programs such as AA for the meantime. But those accomodations should in no doubt be the sole means of solution. These programs do not address the core problems, that is, lack of significance on education, they only make a way to go around that problem. We can help to accomodate by these programs but most importantly we need to address the core cultural issues.
If we move from aggregates to talk about individuals then it shouldn't be the assumption that as soon as we say African American and African American culture we are immediately talking about a person in the ghetto who is downtrodden and that that culture is actually relevant in any significant way to that African American person. African Americans as an aggregate are poorer than whites but that does not mean Africans Americans individually are poorer than others. By applying an aggregate classification to individuals a distorted picture is painted. Many African Americans are descendents of slaves and former salves, but many also immigrated thereafter and had no affiliation to slavery, at least not to American slavery.
