I am not a fan of completely open borders either, my point is more about them just being conceptual lines in dirt subject to continual change.

There is the good, the bad and the ugly of the world and no one owns a franchise on any of that.

It is and always will be the case. There is so much range in human nature but it is this continual negotiation that keeps us evolving. The children today will have vastly different experiences than we had as children.
