The issue with the world view that "a job is an exchange of services" is that it is unsustainable. The sheer time magnitude of work - 40 hours a week + commute for many decades dictates that it is a very significant portion of your life. On top of that on a day-to-day basis the timeslot itself between 9/5 is the best part of the day for the vast majority of people.

Seems like in order to have a deeply fulfilling life you need to have a job that you like and find it deeply meaningful. There is just no way around it, it is too much.
