Sixdogs,
Ahh piece meal labor. Not so long ago we had something similar in CT where tobacco leaves were threaded onto a long string for hanging up in the shed ( large barn ) for drieing. The threading was done by woman who used an open needle on a beefy "sewing" machine. My brother, who oversaw, crews of the woman would take a woman to the hospital to have a needle removed from the finger, sometimes the finger bone, at least once per week.
Your video doesn't include missing body parts in the work bins and everybody still appears to have all their fingers. Scary stuff.
Now answer me this. Why don't American working age adults want to work when clearly other populations are willing to work under these conditions??
