That is what Graeber aims to describe - he's even specifically written about how technology has undermined "meaningful" employment in agriculture and manufacturing - but the problem is his arguments against "bullshit jobs" conflate jobs which don't serve society with jobs whose employees feel they're worthless because they much preferred being poet-musicians. The latter argument, and Graeber's vision of "Hell is a collection of individuals who are spending the bulk of their time working on a task they don’t like and are not especially good at" are extremely susceptible to precisely the "lack of perspective' criticism raised by the OP. And unlike Graeber, I've met corporate lawyers who chose that line of work because they found it interesting and valuable (and I'd hazard the corporate lawyers that draft the worst contract terms and push the hardest for unnecessary litigation really enjoy their jobs)

Sitting in a corporate cubicle churning out CRUD apps on spec for customers you're isolated from probably feels like it's contributing less to society than co-founding a "change the world" startup that fails to achieve product market fit, but the former probably achieves more good for society, even if it's only the sort of good that involves people having to do less paperwork manually...
