We have to face the reality that while all humans are equal at birth - something I firmly believe in - the upbringing may inhibit or express essential traits for certain professions. Some may have mathematical/logical talent by upbringing, some may have musical talent. some may be polymaths, some may be anxious for anything abstract. All have value, and the sooner we acknowledge this, the faster we can accept that there are people deserving more musical, more mathematical or more manual tutoring.
We can't treat billions of individuals as equals, they are individuals. They are not races though, or ethnics, those are dynamic.
