I honestly hate watching bags of bones work and grind well past body comfort, whether necessity or avarice. It's bad, and indicative of social faults, whether at the bottom or the top. Period. Labour should have a hard set figure where the means of production no longer falls under certain cohorts, like most people would like to keep children away from deep fryers. The criterias can be argued, but only under the most advantageous conditions should there be exemptions (skipping grades upward or something). Meat and bone is all we have and it is very susceptible to life conditioning.
