CHILD LABOR IS BAD
Child labor has existed in the U.S. and around the world for a long time. Children often work mostly in factories, and other places. Owners of businesses like children working for them because they could pay them less than the average adult. Children often work in harsh unsanitary conditions, at young ages. Before the 1940's, many children as low as age four worked.
The 1900's was a time when many children worked in the glass making industry. This was bad, because children were working in conditions of extreme heat. Glass, melts at around 4,000 degrees making it unsafe for children to work in these conditions. some other conditions children work in include coal mines, rolling cigarettes.
