Well since you are okay with working for the entire family then that's good. What I am talking about is a different matter. How about those children who are unaware that they are the ones making a living to make the family survive instead of the parents? It does not matter if the child is talented or not. The mere fact that there are people out there who use/abuse their own children to earn money instead of them as parents striving to make money for the entire family.
If the child is talented then it is a separate thing to make them go to contests. If they win anything then it is their money for future use, not the family's sole or main source of income.
