I would be willing to bet that you could halve the HR workforce at many corporations (especially with some effort invested into automating HR functions) and not notice any drops in productivity.
More generally, a lot of "middle management" falls into this category. From what I see, it really looks like a lot of management work is really just make-work created by... other middle managers. Yes, some level of management is necessary to coordinate teams, but from where I sit, I see my manager spending literally 8 hours a day creating PowerPoint presentations that have no meaningful content whatsoever. And the funny thing is, he hates it more than I do! He's a (ex)programmer. He'd rather be writing code! But somehow the organization has decided (as a consequence of some managerial fiat, far above my pay grade) that it is more "productive" for my manager to be making PowerPoint presentations than writing code.
Yes, the phenomenon of bullshit jobs is far worse in government than in the private sector. But it's still here in industry, and the larger and older the industry, the more prevalent it is. Software companies haven't accumulated as much cruft, but that's largely because companies in software tend to die before they have a chance to accumulate the cruft that's present in industries with higher barriers to entry.
EDIT: Tyler Cowen [1] has an excellent term for this phenomenon: "zero marginal product" work.

Plenty of "useless jobs" exist. It comes back to the classic agency problem. What is best for the market/company/shareholders is often not what is best for the employees working at the companies.

All jobs and businesses related to sales and marketing
Wow. I don't think you've ever worked for any business of any size. Sales jobs are usually very well compensated and make the difference between businesses that fail and those that succeed. Hell, Salesforce is a company originally built just to manage salespeople and their process. If you know a way to make them irrelevant you could probably write your own ticket.
