What you're saying basically amounts to "people are blinded to what they love by their need for financial security". This may be true on some level, but anyone can see through it with a modicum of introspection. Or am I giving the average person too much credit?
I'm not the original commenter, but I think you are vastly oversimplifying the situation. Most jobs are not black and white in one category or the other. There are people who will never be completely happy with any job, and there are local maxima, where one might not reasonably expect a better fit to exist.
>Or am I giving the average person too much credit?
Another consideration is that this is an irrelevant question for your average person, or even 99.9% of the population.
