I’m an American who (gasp) doesn’t think slavery is a bad thing. Slavery, by itself, is alright. When people think of slavery they think of the slaves being dressed in rags, if at all, and beaten/tortured/raped/etc. at the master’s will. While that might happen, that’s really the abusive behavior of the master, not an inherent flaw in slavery. So long as the slave owners are held accountable for their slave’s physical and mental well being, nothing’s wrong.
Actually, by your definition of slavery (men employing others to carry out personal work…in exchange for a place to live, food, and learning a trade) I was a slave for several years. I was part of a program called Job Corps, which is a government-run facility that housed, fed, and clothed young people while teaching them a trade. I had to abide by their rules and work long hours maintaining the grounds or washing dishes for a few weeks per year. It didn’t seem all that bad to me…aside from the forced sobriety. Keeping booze from someone should be against the law or something.
I label myself a slave only lightheartedly, though. I realize that true slavery might not be so tolerable, but that doesn’t make it evil, just inconvenient.
