Slavery? Or Something Else?

Looking at the state of African Americans today; Is the single-mother homes (70% of black children grow up without their father in the homes) out of wed-lock births, black women unmarried (I believe 40% of Black women will never be married), Black men incarcerated at disproportionate rates, black on black crime etc. etc.. Are these black social ills the cause of slavery? Or are these phenomenon due to the past 50 60 years? What has changed? What went wrong in our homes, in our commuities, in our selves?
