Love it or hate it... slavery is what helped establish us as an economic powerhouse.

Our ability to cheaply harvest goods helped fuel our industrial revolution.

It sucks... but the truth is that our country wouldn't be nearly as strong if it wasn't for slavery.

Without slavery... all the other issues become a pointless argument. If we didn't import Africans... I don't think there would be nearly the population of Blacks in the U.S. that there is right now.

Possibly, if they weren't slaves, many blacks would have come to America around the same time the Irish did... but I don't think it would be in such great numbers.

P.S. - we would not be an Olympic power-house if not for slavery. We selectively breed great athletes for darn near 110 year.
