My Thoughts of Child Labor

My thoughts of child labor are,that it was unfair that kids 5 years old had to work and do dangerous things for the jobs like working in coal mines with all the coal dust they would breathe in and how fast they had to do it. But I learned that in mills the doors were locked so they could not get out which was bad because there was a fire once but the doors were locked so they had to jump out the window and the net to catch them broke. Some more of my thoughts are that it was unfair that if you were even a second late they would cut your pay and if you lost a finger our two you would still have to work which was unfair. That’s my thoughts and what I learned about child labor. What do you think about it?
