As the saying goes, "History Repeats". It seems that there are some events that we as humans never learn, though the answer has been given to us before.
Take for example, the creation of the C.S.A & K.K.K in the aftermath of the American Civil War to assert "white dominance" in the U.S. While the U.S. had taken steps to protect rights for all races, it is still a growing problem (especially in the south). If we continue to fall into the same problems, we must learn how the previous generations solve the problem, and how we can either reuse or evaluate and create an answer that is suitable to the current generation. In the end, issues will repeat, and it is up to the generation in which the problem arises to deal with it their own way, whether learning from the past, or creating their own path to stop the problem.
