I don't think, and in general believe people label, not things like construction work or care givers as BS jobs.

BS jobs are the ones that only exist to support hordes of people having jobs; middle managers, service industry (all the downtown office worker coffee/lunch/bar/cleaners/maint). And most retail.

Cleaners are a BS job? They're an unpleasant one, perhaps. But that's not a BS job. (For one thing, they often are the ones that restock the toilet paper in the office bathrooms. Think about the implications of that job no longer being done. If we're going to have offices at all, that's not a BS job.)

[Retric]

Service industry jobs like bartenders are directly doing stuff customers actually want and are willing to pay for.

If that doesn’t make the cut then 100% of jobs are BS. You don’t “need” a farmer when you can just plant your own food etc.
