I have the solution to child support, want to hear?

I see your point because a lot of parents who receive child support do not think about the child's future. I think that they should make each parent who receives child support keep receipts of what they are spending the money on and have to show that. I have heard horrible stories where the mom spends it on drugs, and other stupid things. The only problem I see with Social Services getting involved, some states are not equipped for this. What if the non-custodial parent stops working then what? What do you think should happen then?
