Blame Eli Whitney.
I don’t blame any individual. I blame human nature, for its inability to see the truth for so long.
Many of us were not really worthy of the genius and deep understanding of our Founders - they believed that slavery would die out, if the ideals they enshrined in our documents and national spirit were taken to heart. I don’t think they believed it would come to so bloody and destructive a war.
Obviously, many of us still are not worthy.
Here I agree with you again.
