Behind every story of economic / societal development are the workers who made them happen. It was true for ancient societies like China and true for the United States in the early 20th century. Now, it's true for booming emerging market economies like China and India.

The stories of these workers and their harsh realities are sometimes shocking to the rich. In India, one story involves young children who work in brick mines. In the Ratnagiri district, about 200 miles south of the booming city of Mumbai, they carry about 100 bricks out of the mines each day.

They are paid $0.04 per brick, which weighs on average 40 kg each. Below are pictures of Ratnagiri's young brick mine workers.
