Those "ergonomic safety procedures" are one of the reasons the stuff is manufactured in Guatamala. So many of these "feel good" regulations are issued by gov't workers trying to justify their jobs that American companies can't afford to do things here in the USA.
Yes, some safety rules have gone overboard. The answer isn't to junk safety all together.
We are not returning to the 1950's here. We are returning to the 1870's. There is a big difference between, no junk science, put in a hard day's work for a decent wage, that you could get in the 50's and 60's, and a return to children working in sweatshops, for pennies an hour, with no safety, exit doors guarded by armed thugs. Is there no happy middle ground here?
