I never considered this a complex question until recently. I wanted to put it into generic terms and see what kind of responses I got but do it in terms that was a little less loaded. This is largely a social science question regarding concepts like surplus, deprivation, etc.
This is simply an opinion poll. The boys are the same in each scenario, and you can assume that they misbehaved in the same manner. The number of toys never change. The only thing that changes is the cost of punishment. Choose the one you feel treats both boys with the same degree of punishment and maybe explain why.
