actually according to the Tarzan theory, and actual real problems with people lacking in social human contact, he wouldn't be able to make it simply because of the contrast between how he was raised and what society is actually like. Though these both have things with the main character having NO Human social contact, even from parents...
However this being said, I think the kid would end up with being able to do a low end job, something blue collar...
However the social contact with his own age group needs to be helped with, not to mention sex...
He'd still have trouble adjusting to the big city... I know I would and I live in a tiny little town in Montana.
