But here you're contradicting yourself. These aren't bullshit jobs, because if the job was eliminated, it would make a big difference. Say what you will about Amazon, the world would notice if the fleets of trucks departing their warehouses suddenly stopped, because no one was picking the parts to fill them. The people buying those products would notice when they didn't arrive. It may, by your definitions, be a shit job. In fact, it's probably a pretty textbook example of a shit job. But it's not a bullshit job.
