I identify with this article more in a meta-level of how much mental bandwidth one loses to the overhead of having been born
poor:
All those things you worry when you didn't came from a well-to-do family rob mental processing time, thus making it harder to use your time productively to escape further and faster from poverty.
Rich people for example probably never ever entertain those worst case thoughts someone who was born poor usually obsess from time to time, like, "what if this recession I saw on news deepens, I am laid off and can't find a job for months, maybe years? will I become homeless? will my family have food?".
This is mental processing time that wealthy people can use to be creative, to learn something new, to have fun, but for you, it is about a couple hours of extreme anxiety where you can't concentrate enough even to work.
