I live in Oregon. Up until last year, you weren't allowed to pump your own gas in most parts of the state. The law required gas station attendants to do it, as a scheme to keep them employed. The most annoying part of this wasn't the tiny marginal cost, but that it sometimes took forever to get your gas if the attendant was busy. You'd just sit there looking at the pump you weren't allowed to put your credit card into.

You can create laws to keep making work for a class of workers, but it ends up unpopular. Instead of a social safety net as it was intended, it turns into a corrupt drain on society at large, and a relative disadvantage to your economy versus those that are more ... agile, let's say. Check out e.g. the underpaid but overstaffed government bureaucracies and police forces in most Latin American countries. Giving a third of your society badge and a lousy paycheck often does more harm than good.

I don't consider this observation to be right wing (per the sibling post), it's just how things work. While there's nobility in work and psychologically it's better to keep people employed, I'd just as soon give all the gas station attendants a lifelong retirement UBI so they'd get out of the way and let me pump my gas.

Collective union Luddite opposition is one part of why there is so much of a plebeian tier pushback against unions, in the very group that should be fighting for unions with their lives. That and right wing propaganda of course.
