Look at this miner, he is carrying at least 40 kg of coal. He has to walk up a narrow shaft underground, walk a kilometer to a weight station. The more he carries, the more he gets paid. How much? Around $0.20 a trip. From an occupational health perspective, he will develop a "black lungs" disease very soon.
