How long can most young men work 67 hours per week for before going stir-crazy up there or just getting rundown and worn out?
No, you would not do that for the long haul. For a young Trad who has no idea what to do, you work this job during the summer, and after tax take home should be $15,000. That's after all expenses, because one benefit up here is there's no where to spend any money, and no females to spend it on.
So the Trad young lad could then enroll for a 2 year certificate program. Maybe work weekends while in school. Then the second summer he can apprentice for about the same loot, or do another hitch up here if he is hurting for money. Second summer he would make $22/$33 per hour.
After 2 years he's got a cert, great field experience, and on his way to $150,000/yr. at a decent job where he can get married and raise a family. (Starting would be less, but he can get to $150,000 within 10 years). Good jobs available in Oklahoma and Texas for someone with an industrial/technical certificate, with some good options for TLM and you would be near a decent sized town/city.
My son is doing something similar, but he's going for his engineering degree. The field work also gives him hands on experience, which is a big plus.
