The difference between having a job and having a vocation is that a job is some unpleasant work you do in order to make money, with the sole purpose of making money. There are plenty of jobs because there is still a certain amount of dirty work that nobody wants to do, and that therefore they will pay someone to do it. There is essentially less and less of that kind of work because of mechanisation. If you do a job with the sole purpose of making money, you are absurd, because if money becomes the goal–and it does if you work that way–you begin increasingly to confuse it with happiness or with pleasure. Yes, one can take a handful of crisp one dollar bills and practically water your mouth over it, but this is a kind of person who is confused like a Pavlov dog, who salivates on the wrong bell.
