It is natural... if you are talking about Parents using their children as mean of income I don't agree with you ... in general NO PARENTS would like to see their childern as a source of money ! Only the time when they are old then they depend on their children ofcourse, same way the children were depending on them !!

I think it is a duty or say responsibility of every child's to take care of their parents when they become old by all mean ...

 

Very rare situation you might see some examples of parents not loving or caring for their children or putting them into some some so that they can earn money for them ... that could be due to some family problems or due to some social issues !! but again the relationship or love remains in their hearts ....  

 

Corn... I think you should have started a topic of children who desert their parents when they become old an are living on the streets or under the care of govt. or in charity houses !! These cases you will find in MILLIONS but parents not loving their kids or using them as source of income are very few !
