You&#x27;re being downvoted because you&#x27;re being a racist buffoon. Yes, there is genetic variation across traits, this is a fact. That said, we are all heavily influenced by our environments and to discount this incredibly formative factor of all human life is ridiculous. Culture, poverty, exposure to crime, and endless cycle of poor parenting, whatever it may be - there are a million things that can and DO get in the way of someone succeeding far, far before their genetics.
