Better to move on and find a way to get along better and NOT make those same mistakes again.
The way to get along better is to address present-day problems stemming from the history. Unfortunately, precisely the sort of thing that people who claim to want to "move on" from "pointing fingers" and "get along better" have no stomach for, because it involves assessing the history and its effects accurately and honestly, which of course is "complaining" in their world.
Make sure EVERYONE has fair access to a good (not as easy as you think) education and then ensure fairness in hiring practices, legal treatment etc...
Well, okay... that ought to be simple, right?
