Are there any occupations you uniquely oppose the existence of?
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.
Search engine optimizer -- The entire industry, intentionally and with malice aforethought, exists purely to make it more difficult for search engines to provide quality output to search users.
Any role at those finance firms that just buy up other companies to eat their profits. What do you provide? Nothing, you take already baked potatoes and make sure all the shredded cheese is scraped off into your gullet and thats it.
Any position in the for profit medical payment processing profession, it should be single payer through taxes instead.
Any investment position that exists to leech money out of successful companies instead of providing cash to improve the business. Basically any part of.a vulture capital firm.
Any pseudo pretend medical profession that has decades without evidence it works like chiropractors. I'm fine with mediums and other charlatans that at least put up a 'for entertainment purposes only' sign and don't have a history of causing injuries to their clientel.
Anything involving targeted advertising since it relies on scooping up personal data.
Debt collectors. The businesses took the risk when they loaned money or provided some kind of service on credit. Selling debt to collectors who maliciously lie and guilt people into paying money they don't really owe or tricking them into paying debt that would disappear after a period of time is horrible. There are no respectable debt collection companies.
Bathroom attendants - since people got all the high value stuff.
I don't mean people that clean the bathroom etc.
I mean the guy that stands at the sink and makes awkward small talk before handing you a towel you could have got yourself and expects a tip.
EDIT: Y'all I'm pretty sure no one's having sex or shooting up in the bathroom at the fucking Eiffel Tower restaurant in Las Vegas ... Coke - probably. I don't know where anyone else has seen a bathroom attendant, but every place I've seen one at I've been wearing a suit...
Paparazzi, insurance companies (and I work in insurance), pay day loan companies/positions, and whoever cooks the chicken at cane's cause that shit be dry as hell.
War profiteers. If you work for a company like Raytheon or Lockheed Martin then you are doing an incredible amount of harm to the world and I have even less respect than I have for people in the military. These companies are constantly looking to fuel conflicts, destabilize, and pump all sorts of weapons into every corner of the globe. These people are the true scum of the earth, they are among the worst people who have ever lived.
People who evalulate and grade pop-culture collectables like baseball cards, video games, etc.
Imagine having a career based on turning people's collection hobbies into investment opportunities for rich people; making said hobbies unaffordable for the people who actually enjoy the subject matter in the process. You'd have to be a real fucking scumbag to do something like that.
Cops, landlords, the entire advertising industry, anything to do with the stock exchange, PMCs, lobbyists (and by extension most career politicians)...
