You began this by making the dubious claim that "advantages" (purposely vague)

Ok let's define it as a financial advantage, and access to better institutions (such as schools, healthcare, public recreation, local governance). Would you agree that certain demographics have historically enjoyed an advantage in these areas? Would you also agree with the idea that having more financial freedom and access to these institutions allows those communities to raise more wealthy, educated and healthier children? Would you agree that the benefits also effect the grandchildren and eventually their children?

are inhereted from "ancestors" (implying that all white people are genetically guilty)

Whoa, stop right there. When did I ever say "guilty"? What does that even mean? Guilty of what? You're being unnecessarily inflammatory.
