When children are free to go to school, the long-term impact is good enough to offset the associated negative results of sanctions. As such, the people will endure and in the end be stronger for it. Their children will gain educations if they are smart and make the country and their lives better. The problem with child labor in these countries is that people can't look past tomorrow and can't see how schooling would help their children or themselves. Sanctions would be manageable.
I believe that imposing sanctions on the general public in regards to child labor is manageable. For certain, it is not insignificant; rather imposing sanctions can cause a massive domino effect that can trickle the fabric of a global economy. It would be foolish to believe that imposing sanctions would not have any damage to the resources of a certain country. It is not to say that child labor is acceptable, knowing the benefits (albeit small) it has to the economy. It is to say that the effect of imposing sanctions can be sustained if the parties can work on a solution that eliminating child labor will create.
