Seriously, though, I think it helpful to have a job that you believe is doing some good in the world. The world is a much better place than 20, 200, or 2,000 years ago thanks to a lot of people contributing a tiny pebble in the wall of progress.
I like how Cowen discusses this in Stubborn Attachments. Basic message there is, if we can grow the world economy by 3% per year, the world is going to continue to get better thanks to the magic of compounding growth, unless something drastically bad happens. So, if you want to help the human race, contribute.
It's supported in scripture, too. Ecclesiasties talking about taking joy in your work as one of the few things in life with meaning. Paul was a tent maker, Jesus a carpenter (probably a framer as opposed to a furniture builder, but who knows)., many apostles were fishermen. Jesus used their jobs as fishermen as an opportunity to teach, too.
But a job will not provide you with moral values, or ways to interact with friends/neighbors/spouse/kids, or a deeper meaning to life.
When it comes to priorities, I don't consider myself to be a Christian first, then husband second, father third, banker forth, etc. I consider myself to be a Christian husband, a Christian father, a Christian banker, etc.
I just don't see how your job as your identity is going to help you with how you will live the rest of your life. You have to fill that hole with something else besides your work identity.
