Each and every one of us uses our intellect and knowledge in many various ways, some people are of a less or higher IQ, (thats just a gene pool thing,) some are quick to learn, and again there are others who either do not want to learn, or resist change and new technology almost as a norm.
Whatever the rights and wrongs of it, we are all at some stage either, - overawed by someone with say - higher qualifications or an exotic sounding or very technical profession, and mayhap a refined voice.
Or we look down on the "thickos", and we all know they are out there,( just nod, you know you have!) or else we feel somehow superior to someone with a more mundane job, its a normal human condition fortunately or otherwise.
There must be times when you look around at - (eg) work mates, neighbours, even friends, and wonder how many of them would survive in the event of a natural disaster, or serious break down in civilisation.
This is because it is human nature to compare, we do it automatically every single day of our lives, sometimes you feel your top dog, other times you wonder if there is an invisible sign over your head saying "treat me like dirt".
No I am afraid as much as you may wish to legislate, not all people are equal, each and every one of us is an individual, and that will shine through.
Take the race , creed and gender issues out of the equation, put in the laws that protect individual rights, and there will still be those who regularly excell and those who regularly just get along or consistently fail at whatever they do.
The human brain is a very complex device, and each is unique to the individual, and legislation may cause people to give lip service to equallity, but in behind the closed doors and curtains of the brain, there will always be that comparison going on, even subconsciously.
How many times have we as people met someone for the first time, and either took to them straight of, or immediately set up barriers of dislike, or worse still, just wrote them off as being of no consequence, we just compared automatically.
Natural selection and survival of the fittest and most able, is a deeply entrenched primal motivator, stronger in some than others, and with that in mind (no pun intended) no not all people are equal.
