Can it be systemic yet not societal? Like biological origins?
Yeah, I've heard women are biologically programmed to prefer earning less money. JFC, listen to yourself...
"Push button A to get money, or push button B to get more money"
then everyone would push button B. But in reality there are other factors. Like "button B has a slightly higher chance of injuring you". Or "button B can only be pushed late at night".
It's entirely possible that people are biologically programmed to have different risk/effort/reward preference curves.
