I mean, can you or can you not picture your job being done by a pig wearing clothes in a children's book?
Because I can picture a pig with a boater hat and round glasses carrying a pile of half-unspooled film reels, a pair of safety scissors and a roll of tape on their belt.
And before you complain about it being an old-fashioned depiction, the OOP isn't exactly how a modern butcher works either.
The question isn't whether someone in the comments section can imagine the job, it's whether the same 'you' who does the job can imagine the job being done by a pig in a children's book.
Also, if you're complaining about it being unfalsibiable, don't give more examples for them to judge, ask the people defending the joke for counterexamples. That's just logical (in the literal mathematical sense). That is to say, jobs that can't be pictured as something done by pigs in children's books.
There I would say hedge fund managers, health insurance coverage evaluators, and telemarketers.
As for looking down on people for just trying to pay their bills, how do you come to that conclusion? Unemployed people and chronically disabled people don't have real jobs either. Do you look down on them? If not, why assume people are looking down on people who do fake jobs to pay the bills?
Why do you think this post isn't pointing to super morally dubious jobs?
