The point being made here is that "raw talent" is frequently the removal of barriers via socioeconomic factors. The best predictor of whether a child will graduate college is whether their parents also graduated college.
Most "naturally talented" people are "simply" people allowed to reach full human potential due to circumstances of birth, where "less talented" people frequently could have reached similar potential, but for:
- lower socioeconomic status
- less- or un-educated parents who don't know what opportunities to put their children into for maximum growth
- parents who themselves experienced significant trauma as children and didn't have the opportunity to process it due to lack of money or access to mental healthcare, and then subsequently inflict similar trauma on their own children
The lower socioeconomic status one in particular contains a host of other potential potential-limiters:
- less money for healthy food (or enough food at all) means less growth potential and worse overall health for the rest of your life
- if your parents don't have money for the equipment, you likely won't be allowed to participate in sports (happened to my wife) which means your brain will miss critical early wiring opportunities with the sport-specific mechanical tasks, which will result in lower potential skill ceiling later in life
- no money for travel means less exposure to world cultures, and unless living a in large city less exposure to foreign languages, and exposure to foreign languages as an infant is critical for later foreign language success due to pruning of connections for unused phonemes during early development.
There are many, many more things that go into the development of "raw talent" I haven't even touched on beyond "just" parent socioeconomic status, like poor people being more likely to have to live near major roadways and its influence on the rate of asthma in children.
The takeaway here is that very often people with "raw talent" weren't born that way, they were simply allowed to grow.
