Where I am, it's not uncommon to see an electrician or millwright working 70+ hour weeks to meet deadlines or make emergency repairs.
Moreover, it's been my experience that people in non-trade work (particularly non-exempt STEM workers) often work just as much overtime and don't even get paid for the pleasure. Granted, their base salaries are generally higher, but a tradesman working similar hours can approach or surpass that. (I say this is I sit at 2:40am waiting for code to compile...)
Non-sequitor: I misread that first word in your comment as "Transgenders" and was flabbergasted halfway into that first paragraph until I went back and re-read it :D
Where precisely is the trouble for the tradeperson? This is something for the owner of the project to worry about, not someone who does the work.
This is much different from my experience. I see office workers (the startup crowd especially) working crazy hours, practically living at the office, and actually bragging about it.
Meanwhile, most trades jobs are unionized. So you might be working long hours in an emergency, but you're getting paid time-and-a-half at least. Outside of emergencies, you get to punch the clock, and leave work at work.
The grass is always greener. Especially if you look outside startups (and outside software engineering), I would guess the overwhelming majority of office jobs occur around a roughly 9-5 schedule without significant overtime. There's a reason rush hour is rush hour.
