Given that he was inventing medical technology in his mid-teens, I'd say he came out pretty well on the brains side, so it's not like he doesn't have advantages. I can see being bitter, but that doesn't really add much weight to his arguments.

Aside from this, most if not all the people standing there have been literally tortured, imprisoned, kicked out of families, set upon by mobs, damn near killed (and I'm pretty sure actually killed) many times over since their early teens, so you can't really say they've had entirely cushy lives.
