That explains fairly well, why rich countries all have more-or-less similar health and safety standards despite very different histories and especially histories of labour activism, and why poor countries fare worse in this respect--even if some of them have laws on the books that are just as strict.

I've spent a few weeks on one, so not zero, but not a lot.
Note that I simplified greatly a real assembly line, and there are lots of different lines with different configurations. Nearly everything is multiple lines. There are often buffers along the way so that you can get ahead of the line by a little (or if you need to use the restroom the line continues). Sometimes there are two people in a station with the understanding that if both are perfect they are 80-90% busy (or some such number), but if someone is slow the other can help up. Lines often go slower than possible because of safety. There are likely more issues, but there is a point where the line is waiting on the slow person.
I'm not a great expert on assembly lines, to be honest. But two things:
- From theoretical considerations (less important): you can be better not just by improving average speed, but also by reducing variance (ie being more reliable) and improving quality.
- A practical consideration (more important): from what I recall, even people on assembly lines are often paid piece rates. Ie they are paid more or less proportional to their output. Assuming companies aren't complete idiots, we can assume that they have a good reason for rewarding individuals for higher output? That seems to be in at least mild contradiction to "The assembly line is as good as the worst/slowest person on it, [...]"

Btw, health and safety are what economists call a 'normal good'. See https://en.wikipedia.org/wiki/Normal_good
