Is there a word for a job that doesn't actually contribute to increasing productivity in a country and even if you make them disappear, it won't change the way people live or the country's economical prosperity for example being a street vendor, a busker, a clergyman who just preaches and talks around and receives money, fortunetellers, or a person who sells cigars along the street (like a vendor). Usually these jobs are frowned upon by economists.
In my native language there is a word for it that its literal translation is a pseudo-job. Is there an English word for this kind of jobs?
Edit: To make the meaning clearer I add an example from a context: I saw a local newspaper headline going like this: "Our skilled labor force now in danger of doing pseudo-jobs." In the article it argues that we cannot provide our skilled experts with job opportunities that they can benefit us most. As a result they start pseudo-jobs like being mourners, vendors, fortune tellers, flyer distributors, etc.
If you want to write this piece of news in English, how would you go?
