Well you would be right in thinking that bevavior mod doesn't have to be effective to benefit the program owners.
The program owners befit by the income from the business (they get paid). If the business doesn't do well then they will benefit less. So there is an incentive to make every child as successful as possible and do a little bit better than the next program.
We certainly can't discount that money does motivate those applications which best suit the investors.
We always need to keep in mind that people do what they do and are motivated by money. A good test of that would be to stop paying hospital employees and doctors and then see how many people are still working in the hospital after a month. There are many compassionate people in the world but we all need to profit from what we do to survive unless we want to be supported by the government.
I'm more interested in what you would consider abusive in this sense.
Any type of physical violence to try to change a kids behavior would be considered abusive in my opinion. Say, hitting a child with a stick every-time they made a mistake. This would not be considered positive feedback and would not further build a child's self esteem or self worth.
