You can't. However, it's been many years and you can't continually blame slavery for struggles that continue to this day. You weren't a slave, your parents weren't slaves, your grandparents weren't slaves, your great grandparents weren't slaves, your great great grandparents likely weren't slaves. How can you use that as an excuse for anything to this day? There are many ways for you, despite whatever kind of upbringing you had, to make something of yourself. It requires hard work and dedication though which unfortunately seems to be something many young people today, regardless of race, are severely lacking in. Nothing is their fault and they want everything handed to them. Change that and good things can happen.
