I try to see problems as much as possible from the point of view of “what can I actually do about it?” You can’t, for example, influence how rich your parents are or who their friends are.
But there are huge default barriers you can influence after the fact.
First, it’s easier to do something when you’ve seen someone else do it.
People thought the human body couldn’t run a mile in less than four minutes until Roger Bannister did it in 1954. Once he had shown it was possible, two months later two other runners did it in the same race.
It’s the same with being raised by parents who got rich. You saw what they did, you know it can be done.
On the other hand, if you don’t know anyone who’s gone to college you might not know how that process works or even consider trying.
20 years ago I wouldn’t have much advice. But today you can look up whoever you want and just straight up ask them “how can I do what you do?”
(Pro tip: don’t talk to famous people, talk to the people one wrung below. Or talk to people who used to be famous but are now out of the limelight. They’ll be easier easier to get in touch with.)
