To my mind, there are so many socially and materially unproductive (but often highly paid) jobs now, which never existed before and which the world would probably not miss : marketing executives, public relations officers, personal trainers, image consultants, brand managers, event organisers, telemarketers, "chuggers", marketing psychologists and lobbyists (the last two being not only pointless but, in my opinion, manipulative and unethical), etc, etc.
It seems to me the jobs that are absolutely essential or which we would find it very inconvenient to do without - such as farmers, engineers, teaching assistants, cleaners, gardeners, carers, child care workers, nurses, street cleaners, dustmen, factory workers, bus, train and coach drivers, laboratory technicians, shop workers, paramedics, fire officers, emergency call centre operators, etc, etc, often have lower status and are under paid.
I think one of the reasons the modern world has become more and more obsessed with the notion that making money (by almost whatever means) is the most important thing; thus year on year profits must continue to increase. Therefore all sorts of strategies must be used to persuade people that they must buy stuff they don't need - and to keep buying it in order to ensure that our economy is "healthy". This calls for a whole range of marketeers - from marketing strategists, psychologists, brand managers, etc etc, to more niche specialties such as food photographers.
A very mixed up world - on the one hand being urged to keep buying goods and services in order to maintain "growth". On the other, being frowned upon for over-consumption of valuable resources, leading also to disposal problems - both of which damage the environment.
