Slavery.. Good or Bad thing?

BAD VERY BAD i think that all people have straigth to decide taht the like make with you live if you like work for other person good but if any moment you like change this work you hace all straigth that make this

Of course is a bad thing. I heard that they were treated so bad. Even going to the toilet is a big matter for the boss and wont allow them to do so. I am really strongly against slavery, you are not actually thinking about them as humankind, people who conduct slavery treat them as robot or animal. They also get paid so little of in the old days, there are people who does not get paid. Just work for foreign country that invade the country. The condition was unimaginable as I wasnt born yet.

Of course it was a good thing that slavery was abolished. The word "duh" comes to mind.
