Engineering talent is in such high demand, the only reason anyone would work a death march is masochism. I mean, we get paid 5x the average US salary. We make enough to retire in our thirties. Working stupid hours in this environment is a choice.
e: engineers, not people in general.
30s is a bit aggressive, tho ;)
It's not common but the math behind it is solid. You just have to not live like most other people do.
Compound interest is something that more people should really understand.
My point is that we are one of the few professions where there is NO reason to work ourselves to death. We are in a position to insist on good working conditions or to stop working entirely IF we so choose to do so.
You would be shocked at the passive income you can have in your 30s if you actually get to keep some of the stuff you build.
