Well, OK, that's all good for him, but I doubt most people who work over 50 hours are as happy about that as he was.
My experience in construction was that a plurality of 50hrs+/week guys were unhappy about their hours but worked them to finance an aspirational lifestyle.
e.g. My brother in-law (a pipefitter) complains bitterly about having to work to "make ends" meet, but lives in a $500,000 house, drives a $60,000 truck and parties every weekend. I suspect he could get by on 40 hours/week if he lived my lifestyle
