Fair questions.
But we answer those at the moment with equally inadequate answers: your parents owned the nice mansion, so you get it (though that also includes "so your older brother gets it" just to be really unfair). Also on the other end of the spectrum: your parents messed up your education and traumatised you, so no mansion for you.
It would be good to work out some system that could answer these questions on a better basis than that.
Exactly. "Hey you are being traumatized, which in itself sucks because of the sheer amount of pain needed get there. And because of your traumas, you'll now also have a lot more struggle in your life as an added bonus. Plus, people will only think you're lazy, awkward, just "dont have it", or whatever other combination of medieval-level psychology knowledge snippet."
