I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
This is pretty much my list. Middlemen. I wouldn’t say absolutely without value but it’s gotten out of hand.
There are some middlemen positions that add value, like many distributors who smooth out the transportation between manufacturing and retail, but there sure are a lot that insert themselves into the supply chain to suck money out without adding anything.
