If you, as a machinist, can get to live in a lower-price region, go hunting and fishing or just traipsing through the woods instead of doing that next release drive, build or repair your own HVAC or PV array + storage and get to raise a family while doing so I'd say that's worth quite a bit of that discrepancy in salary. You'll get the added advantage of seeing your handiwork being used and lasting for years to decades instead of being replaced in a few months or never used at all.

Replace 'machinist' with a choice of other hands-on 'blue collar' professions for the same effect. Even better is to replace it with a profession which allows you to combine manual dexterity with software development.

Or do as I did and buy a farm which allows you to flex all your muscles - mental as well as physical.
