In 1997, economist Jeffrey Sachs spoke publicly about sweatshops in developing nations, and the BENEFITS of having them in the world. Sachs argued that it's not that we have too many sweatshops, it's that the world actually has too few. Sachs says that sweatshops, although have poor working conditions compared to a developed nations work conditions, provide more 'good' than they do 'bad'.
Sachs says that the jobs provided by sweatshops often have better working conditions than other jobs provided in that country. He later went on to argue that if the job wasn't an improvement from the workers previous living conditions, than they wouldn't continue to work at the factory.
Jeffrey Sachs also makes the point that children are unable to work pretty much anywhere else - but they genuinely need the money to survive. When a sweatshop closes and relocates, many children and teenagers are without an income which they so desperately need - so most of them resort to street hustling, stealing, and prostitution.
Sachs goes on to argue a variety of points including sweatshops help build the developing nations economy, and the fact that eventually, the wages will rise in these factories to the point where they are equal to minimum wage in places like America.
