There are plenty of smart people who do manual and blue collar labor. A lot of us don’t want to sit behind a desk all day. I think I’d rather live under a bridge.
BTW. I'm one of the High IQ crowd too
(For all the good that's ever done me)
My brother had an IQ of 148, he would have lived under a bridge before sitting behind a desk. Dropped out of HS the beginning of his junior year, went to work in construction and hot tar roofing, rode with the Hells Angels for awhile.
He never minded hard, back breaking work but couldn’t handle authority or structure. I think the one thing he really enjoyed was playing and writing computer games during the off season, back in the Commadore era.
