Not disagreeing with you, but there are 8 billion people (at least) on this planet, we all need something to do, no? There is probably only a fraction of work that is actually meaningful (growing food, healing others...) and a big chunk is probably junk work or mostly junk ("social media manager" - how many of these do we need and do we need 40 hours a week for this?) but these jobs also keep people employed, so maybe in that sense, they are meaningful?
