It is what it is. Humans evolved in tribes and thus they have high tribal instincts. Characteristic of that tribal nature is that tribes that changed too rapidly died and tribes that changed too slowly also died. The correct balance thrived, but it is on the side of very slow change. This is what made the current humans exist. Otherwise, we'd be something different. So, as it is, if we want humanity to change there's only two things that will do it. Either what succeeds in breeding changes or technological changes in the environment push certain behaviors. Only the first creates innate change. The second lasts as long as it causes changes in the first.
