Race realism died long ago when education mattered far most than genetics, at least on behaviour.

- African tribe culture not used to give playtime/talk to kids when they are babies: behavioural problems raise at adulthood.

- Western world used to it, no matter the class or money: potentially good adulthood.

The problem is that the wealthy class didn't like to have educated citizens in Africa; but a brute workforce, like donkeys, to get nearly free raw goods.
