What I hate about his argument--and yours--is that there were countries in Africa willing to sell their own people into slavery which got the attention of other countries that in turn made it extremely lucrative for them to do so (to the point of people getting arrested for minor offences getting sold off).  tl;dr: You're both right. Everyone was fucked.
