That's speaking of extreme cases of risk to health, which are NOT rare, btw. Better to live another day as a poor man and a poor family.
I also suggest that people delude themselves about how acceptable, or tolerable a bad job is just because it pays well, and their spending habits and family's spending habits have adjusted to same. And by "bad job" in this latter case I include jobs where you are not all that you can be -- were your personal "pursuit of happiness" has stalled, become atrophied. In those cases, I beg you to quit, come hazard and havoc, yet bear to it and grow.
And then, if you are too sensitively constituted to withstand such a bold course, then at least have some respect and even admiration for those who do! For they are still trying, were you have stopped, and found "tolerable" to be enough of a comfort.
My father had several jobs when I was growing up that he hated. He never quit any of them until he had a new one, because he had seven children to feed and keep housed. Should he have quit, then tried to more or less find something that suited him, let us lose our home and be fed by charity or the government? Because that’s what his brother did. My uncle could never find a job that “fit” him. Finally he decided that it was his family that didn’t “fit” him so he left them too. My cousins - well, the lucky ones got kicked out of their family at 14 and 17, the unlucky ones we don’t know where they are.
I have no admiration whatsoever for a “man” who would allow his family to go hungry, have inadequate clothes and shelter, or suffer in other ways because his job is so horrible.
