" When the price of coal falls because production has increased while demand has remained unaltered, then, for example, those retailers are involved who have taken supplies from the wholesale dealers at the old higher price but are now able to dispose of them only at the new and lower price. But this alone will not account for all the social changes brought about by the increase of production of coal. The increase in the supply of coal will have improved the economic position of the community. "
