This is sort of like arguing that just because you did not actively forbid your child from reading, but merely failed to provide him with books or show him how to read them, that it is his fault for being illiterate.
Not quite. To follow your analogy it is like sorrunding children with books, encouraging those who try to read and punishing those who don't. Over many generations. Yes they will all be literate.
I assume here that this is/ip thing gives advantage to those who have it and puts those who don't at a disadvantage.
