I've worked in both tech and construction. Never seen a tech worker go home and come back with the soles of their shoes resoled overnight because they didn't have a better option for work tomorrow.

Is that the best option? Generally no, it's probably not worth your time to do things that you don't specialize in. But at some point, you run out of hours to profit from the things you specialize in, and you still need something, so you figure it out. You do your oil changes, and fix your shoes and repair things even when they would generally considered 'totaled'. You miss work or at least hours on days when your late model car doesn't start. You take care of your own house repairs and yardwork, if your lucky enough to own something your landlord's yard and maintenance work more likely. And this is all off hours stuff because that's the option you have.

I've worked so much less in tech, yeah the hours can be long and oncall sucks. But I end up being able to redirect all my effort into the thing I'm specialized in and that I get paid the most to do. Which means I can pay to have my boots resoled, or just buy new ones, I take my (newer cars that always start) to the dealer every 6 months. I can pay a premium for delivery of food and staples, I can hire help around the house for anything from lawn care to tree trimming to roof repairs.

When I left the trades, 50 hours was generally required and 60 was becoming the norm. I'm not working any more in tech at work, but I work a lot lest to have a better life outside of work. It's just night and day.
