Isn't that also somewhat culture-based, especially in a SFFnal sense? I'm thinking of the Quaddies from the Vorkosigan Saga verse, a society defined by the work gang, the word "work" as the highest praise, and the idea of slacking off in any way abhorrent to them. I've got something like that in what I'm worldbuilding, where not being able to deal with the hostile environment is a highly undesirable trait. But with them, discipline and self-denial are build hard into their whole social system, so I think it makes sense.
