Historically, many people who work in the underground turqoise mining industry have died prematurely of "blue lung disease," cause by the turqoise dust. Now a brand new technology filters out 100% of the dust that is produced while mining. TFU: Because most workers already suffer from the disease, the new safer technology will not lead immediately to any reduction in the compensating wage differential associated with the hazards of the blue lung disease.
False: since the workers are already being paid a hazard pay to compensate them for the increased danger, the introduction of the new technology would eliminate the need for this extra pay. Those workers who already have the disease would be replaced by workers who aren't infected and would wear the new gear. These workers would be paid their MPL, which would not include hazard pay.
