Sad very sad.
However, in some countries, this is common.
In Cambodia, there are beggar families. The heads of the families usually keep the children starved all the time so when the families beg, they get more money.
Same with a child with sickness, the children stay sick, the parents do not seek medical treatment, clinics, etc... because they are the "money makers" by being sick.
Many of my friends have gone to Cambodia for business, and that is very commonplace there
Another common thing is if you are poorer, to have your teenage/preteen daughter or sometimes son kidnapped by richer, more powerful people to become a prostitute.
This has happened to some of our church members in Cambodia. If they do get the money for the ransom, (usually 3 or 4 years salary), they do get the child back, but due to the emotional, physical scars, the families are hurt all around.
