Plus, America wasn't even good at slaving.

God had to show up in Egypt. And they had the pyramids built by then.
Plus the Slavs got so slaved that they became the generic brand name for chattel.

honestly, all the guilt is silly. some Euros went to Africa and found a functioning and mature international slave market. 
They bought some.
not that special guys. settle down.
