Hmm, am a bit confused by what you're asking, OP (but then again I have ben watching T4 all morning, so have probably lostsome brain cells
)
I think you are asking if you have a better quality of life because you don't have to stress about your job, because you can always get another one?
If I am right, then I think it depends on what you call 'better quality of life'. In some ways I would say yes, not feelng stressed about work compared to those who are constantly anxous about it would make your quality of life better.
OTOH, working in a job that you love and thrive on is incredibly fulfilling and creates a whole future of ambitions and goals, as well as improving self-esteem, etc etc. I would say that my job adds hugely to my quality of life because although I work very hard, I love it and all the people it brings me into contact with.
Also, money can be a big decider on quality of life, IMO. Not being a slave to it, or confusing money with success or status, but having disposable income lessens the stress of bills, etc and affords some luxuries whih can significantly improve quality of life. (hobbies, holidays, etc)
Depends!
