Straight from the dawn of mass manufacturing. No material handing at all-- you just pay some guy ten cents an hour to pick up a part and walk it from one station to another. Each workstation is 1920s-style full manual lathes and mills with hard fixturing. You could ask for material traceability documentation if you wanted to hear a chorus of laughter: the metal on those sprockets appears to be random scrap sheet fresh from the side of the road.
The sprockets in particular could be done with a single progressive stamping press. It would replace the jobs of what appears to be 20 separate people and would cost 100x what they would make in their entire life.

More like, if you want to get a fake document. That happened all the time to my dad. He needed a certain grade of steel that was rated for use in nuclear reactors, and would get completely unqualified materials that had been stamped with whatever grade he’d requested.
I'm in total awe of manufacturing processes both automated and manual. When watching the Japanese factory I could tell that safety was a high priority. I've heard stories about metal pouring gone wrong, and could see that that process was well controlled.
In the sprocket manufacturing shop, I kept thinking of ways those processes could go wrong. In particular that first press with the foot pedal made me cringe. Yet the shop seemed successful, and they produced sprockets. I wouldn't care to guess how many sprockets per finger that place averages though.
Either way, finding a process that can be repeated for profit seems magical. It's a far cry from the uncertainty that seems so widespread right now.
I'm totally hooked on these (pakistani?) videos. It's sort of relaxing, and cheap edutainment.
What I've seen is that lots of these videos are uploaded to many YouTube channels (ripped from one to the other, or having the same people behind, I don't know). They don't even have that many views, and don't post super frequently, I'm not sure they're making a living through ad revenue. I would love to read a piece on who's behind these videos, it's very intriguing.
These do look like from Pakistan. There is a story (no idea how true) that goes around about expertise of some of these mechanics that one of the nuclear scientists (Abdul Qadeer probably) needed a cylinder part but the manufacturing plant wasn't getting it right. He eventually hired one of these expert local mechanics to make it for him and that guy made it perfectly for him.
