My experience: Psychological orphans with a basic income. "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…
Though there is the "upper class" founder background that still had shitty parents and something to prove, and often they can get really far because of the $ and connections, though often have the issue that their alternative life is a bit "too easy" so they don't execute hard enough / close enough, or they just give up.
