digging our heals in, or working without passion or what if we all loved our jobs

We have all seen a person who is not happy with his or her job. We probably have all had a job that we were less than thrilled about. The purpose here is not to talk about a J-O-B job, the kind of job you do because you have to. Instead, I am talking about people who find themselves in a field or particular atmosphere where they once felt called, but now have lost all passion. Let me take it a step farther because I know that there are some very hard jobs out there that are physically and mentally draining. At times in these jobs, people may find that they loose sight of what originally made them take the job, or go into a particular field. So, it can be expected to get frustrated while working in a very demanding field. It may even be best for you to think about quitting. I am not talking about these people.
Who I am talking about are the lifers. The ones who say if I can hold this together for 20 more years I can retire. That may be extreme, but you get the point. Why devote your life day in and day out to something that you do not love? Now, that is a tricky question. Is it possible to not love something you are called to do? I would say yes, but I do not think that God intends for it to be that way. I believe that there are people who are doing what they are supposed to be doing with their life, but are unhappy. Why would that be? Possibly and probably because they are looking to find their joy in their circumstances or they are too focused on self and not on others.
I may still be getting off track from what I originally intended to talk about. Is it worth being miserable doing a job you do not like and may not be called to do, just so you can have good benefits and retirement? When there is a question over the need to provide for your family, the answer may be yes. It should also be stated that some may go to work with the best attitude everyday, but a boss or coworker may be the cause of stress or unhappiness.
One more little point... We are so concerned with being able to retire and have good dental plans that we will go to jobs we truly do not like and may should have never began in the first place.
What if there was no company retirement systems and no social security? What if everyone worked hard and productive lives, and took care of their own retirement? Would we be happier people pursuing our dreams instead a peple jus dreaming about being able to retire? I believe that many people never go and do "it" whatever that "it" is for them because they may risk hurting their retirement. I believe this focus of being able to retire after 25 or 30 years of work has made us a more complacent country. If we only work so we can retire and our kids can have straight teeth (a reference back to benefits/dental....I thought it was funny), why are we working at all.
The strong, working class part of our country looks down on the many who are riding the wagon, but never pushing because they do not want to get out there and work. Well, many of that working class, if asked, would also say that they don't want to work.
Just added to the title and I leave you with this. What if we all loved our jobs?

I wrote earlier that my wife would be proofreading. As you can tell she has decided not to. I believe she is trying use the old give a man a fish, teach a man to fish proverb.
Sorry
