Slaves on a plantation, 19th Century immigrant unskilled workers, children in early industrial revolution factories. Sadly, we read that this is still happening, especially with young women from Asia, Africa and Eastern Europe brought to the US by unscrupulous importers of quasi-slave labor. Standard Factory Job.
