Developed country and Future growth ?

Thoughts triggered after hearing a colleague who says his 22 year old, high school topper son, dropped out and is working in Fry's / Gas station (part time).

I was like if he is brilliant in studies why not exhaling in professional fields, he was like he can pay for apt / car / expenses and does care.

If basic necessities are available with doing odd jobs, who will take initiatives in various fields and continue one's >> family >> Nation's >> World's growth..not that am against odd jobs... but then can we as a nation / human being grow or imporve ? Make me think the hypotizism of either becoming doctor or engineer was not wrong, or was it ?

thoughts?
