Another way to spot anti-jobs is to to observe the effects of Covid restrictions and look for areas where removing workers or tasks made no impact on performance, or even improved it. Take waiters. In America there are around 2 million people doing this job (1.4% of all employment). The experience of Covid lockdowns shows that much of what waiters do can be done better by pasting a QR code to tables for customers to scan to visit the menu webpage and order and pay directly. Having learned this, it would be ridiculous to go back to employing people to waste their time and their customers' by doing such fundamentally needless work. We still need some waiters to bring the food and drink we ordered (for now), but we don't need nearly as many because we don't need to employ people to ask us what we want and then tell someone else to make it.
