I've failed at teaching my children the benefit of having a strong work ethic, opting to do the chores myself so they'll be done the way I like them done.
That's what led me to researching the types of horrible, dangerous jobs that kids from four-years-old to sixteen did in previous centuries.
How were people okay with kids spending 12 hours a day in coal mines or crammed into chimneys? What sorts of dangers did they face? And who would help put an end to it?
