Equality...What on earth is that?!

EQUALITY. I've heard of it, but never seen it with my own two naked eyes. It's like peace, we feel it within ourselves, but we never experienced it. So, now, I wonder if equality ever existed. Ever since the first day of life, there was always a leader within animal kingdom or humans. No one was always treated equal. There was and always has been a "king." Did someone make up equality? Was it something they felt? I like to believe we are fooled by our own minds. We cannot find peace because we can't make peace within ourselves. We cannot love someone before loving ourselves. SO MY QUESTION IS : IS EQUALITY A NARCISSIST THING?
