"Psychological orphans" i.e. kids who had shitty parents and learned to adapt to survive. Then this behavior became a habit and a game.
"Basic income" i.e. kids from middle and upper middle class backgrounds so there was no food poverty in the family and long term thinking was possible by the kid, even in the context of the dysfunctional setting.
The above is true for me and all of the high growth tech founders I know on a very personal level (could be selection bias in who I connect deeply with though).
