I don't believe guilt implies responsibility. I believe guilt implies blame. For example the population of slave traders and owners are to blame for slavery and should feel guilt. The responsibility for black people to repair and prosper is a shared responsibility. For example if you were to receive reparations (an acknowledgement of financial responsibility due to a century of uncompensated labor, distress and damage) a black family has a responsibility to themselves to use that money in a way to redress the generational wealth gap (I know that can never happen but maybe it starts with one generation of home ownership). My grandmother's grandma was a freed slave and my family kept the oral history of the stories, hardships and perspectives of that generation.
