I like this superficially, but it doesn’t seem to address depper meanings of OPs question.

Our experiences in youth shape our framework for evaluating the future. For example, if no one in your family went to university, you would likely not ever have considered it yourself. Conversely, if your parents talked about their experiences in qualifying, selecting a school and program, the experiece of it all, the person’s perception of the possible becomes greater.

Just like a poor kid has much less ability to start the next Amazon than did a rich kids who is a self made man with a large loan from his parents.

If everything you know is a black circle, and what you can push through and learn and discover yourself is a slightly larger white circle that is 10% bigger than the original. Consider that two people of equal health intellect and aptitudes will have different potentials based on upbringing. 10% of 100 of the poor child achieves 10 units of life’s adventure. The rich kid’s circle of experience because of enrichment from their privileged upbringing starts at 200. 10% of 200 = 20 units of adventure from the same abilities.
