Child labourers: Who was first to call a child to work?

Not many options when you are a
Child and home not as many homes
Where mother, father, single parent are
Able to raise you without the damaging
Need for their child to chip in and
Make money to keep the family fed.
Economies are different; lives we live
Are different... child labourers are real
Even now in our time. Sad to know that
Some die at a young age worn out due
To hard labour - and other children grow
Up healthy and spirited because the
Father, Mother you had grew up in a cast
System greater than your own.
