While it may be boring to someone who use used to doing knowledge work, there are a lot of people who need jobs who aren’t going to be doing knowledge work. They need something.
I worked fast food for a shift before I quit. I found that much more boring and hated it much more than the factory. I’d rather see people employed making stuff domestically rather than have yet another drive-thru window in town.
I grew up in a small town with two fairly decent sized factories. That was a solid job prospect for a lot of people coming out or high school that didn’t know what else they could do. It gave those kids options and kept them in town where they could buy a house, raise a family, and spend money supporting other local businesses. Now they’re both closed and the city is hunting for ways to bring businesses to town. My brother-in-law is driving 100+ miles per day to drive to an area with more jobs opportunities. I’m sure if there was a local factory gig he’d probably take it and save a ton on gas, not to mention getting back 10 hours per week of his time.
