Why did many factory owners in the late 1800s hire children rather than adults?

Factory owners used child labour because, quite simply, it was cheaper. Children worked for less than adults, and their parents were often happy to send them off to work, as the lower classes did not value education. Many men lost work when machines were introduced, as machines could do more work in less time, so if the children had the opportunity to work and earn money, they did.

The owners of the factory preferred children rather than adults in the late 1800's because they could be less for two children rather than one adults. they can save more money and there is no child labor in late 1800's. the owners of the factory's main target were the orphans, they didn't have to pay them just let them stay in a place and give them food.
