Of course I don't, no one alive today does. However that past isn't so distant. As a young child my mother knew some of our family's former slaves. They were of course quite old by then, but my mother remembered them well and told us about them. And I had a great great aunt, Sarah Pamela Williams , who wrote about her life, and casually mentioned the house slaves. It was recently reprinted

I don't have much direct knowledge as to how our family slaves were treated. The family mythology was that they were treated well, but I am skeptical. I have a copy of a letter written to my great great great grandmother complaining about having to sell Sarah to help pay for a move. So it isn't all so "distant" to me.
This slavery allowed the owners to buy, sell, and abuse people without much, if any, legal recourse. My ancestors, people who's names I know, pictures I have, and grew up hearing about, probably did some of that.
I just don't see that as the same thing as people being trapped in jobs, I know people had it hard, particularly in the depression, but just not the same.
