Yes, it would be very hard to eradicate the existence of child labour. Taking a look at how long it has existed will tell one how big a task it is to eradicate.

That being said, one of the major causes especially for families in poverty. In a few cases, parents allow their children to follow strangers in search of greener pastures hoping the lineage story can change.

Unfortunately, some families end up not seeing their loved ones again. It's pathetic, poverty is a big factor and we can start from there to limit child labour in our society.
