The very point of teaching history is to prevent the worst of things from being repeated. Problems are exposed when some people disagree about what elements of the past are mistakes.
I will say that in my case, I ended up quite different from my father in world view and in life path. So I do not think everyone is trapped in that cycle. And we tend to learn from peers as well or better than our elders, so a few breaking the molds are all that is really needed to enact change from generation to generation. We just have to hope that newer generations seek to spill from those broken molds in positive directions.
Through the span of history, we live in an Era of relative calm and peace. We have definition seen some dips and setbacks, but when measured against centuries we are still in a positive trend.
