What does Ike claim is the curse that has landed in the South?

According to Ike, the curse that has infiltrated the South is the idea the man can own the land. This idea was only brought about when the White settlers moved into the South from Europe and taught the Native Americans what it meant to own things. Before this time, the Native Americans had not concept of owning land, and he finds it shameful that many Indian chiefs made themselves rich selling land which they never owned in the first place.
