This is the entire premise of the Golgafrinchan Ark Fleet Ship B, which Douglas Adams wrote about 25 years earlier. But every conservative parent has made jokes about getting a degree "underwater basket weaving" for as long as I can remember.

I think real bullshit jobs are, for example, how third-generation children of billionaires get CEO roles on fictional companies / non-profits only to receive insane compensation, while the board does all the work. Just look at any modern dynastic family in the US, ignoring even the famous names.
