Keynes conjecture was also blatantly off in assumptions about automatability, divisability of work across multiple people (and overhead), apitude requirements, as nice as a 15 hour work week would be. The complaints about "usefulness" of job in direct utility are also shortsighted and miss part of why planned systems have a history of failure in farms and consumer good supply. Just because you don't understand something doesn't mean it isn't important. Looking at an economy from either a worker's or an owner's view is ironically blinkered - the underlying system is what gives utility and wages to both. A pipeline between supply and demand may print money but adding in loops and needless length (as opposed to say acceleration constraints) wouldn't serve either interest long term. Actual bullshit jobs certainly exist and imply a larger scale which can support the load and either enough systemic scale efficiency to counteract the local or just plain a lack of sufficient competitors who would gain an edge from doing away with the bullshit and prosporing or finding out the "bullshit" is actually important.
