Review the chapters that describe Lyddie's work experience, especially the chapters in which she is doing factory work. The conditions in the factory are exceedingly poor and border on inhumane. Also, the fact that Lyddie is a child and she is being forced to do adult work is ethically wrong. She is made to work for long hours, with little food, and no real breaks. She is also making far less money than she deserves. She is, essentially, being treated like a slave.
Unfortunately, during the time period that this story takes place in, there were no child labor laws to protect children from being taken advantage of; if Lyddie lived in the U.S. today, her employers would be charged with abuse and numerous other crimes.
