It would be easy to prove that the tax on the community when the wages are raised in any trade, affects the whole public as well as those directly employing the workers in that trade; but it seems too plain to require proof. The main point we now wish to show, is that any increase in the wages of labor over that received under ordinary competition must be paid by the community, just as much as any increase in the price of coal, iron, copper, wood, wheat, or any other commodity must be paid by consumers at large. Nor does the injury to the community stop here, by any means. We saw that the advance of prices by the linseed oil trust was an injury to all those who, on that account, were obliged to forego painting; and that it thus caused a further injury to painters, paint-makers, and even those employed in the building trade. But the increase in the price of the bricklayers' work has results no less important. Not only is injury done to those who build and have to pay more for their buildings, but many are prevented from building on account of the increased cost. If we argue according to a prevalent method, we may say that this reduced activity in the building trade will cause stagnation among allied trades with corresponding loss of employment. Again, as a less number of houses are built, and those which are built are more expensive, rents are certain to rise, which means that the poor man must pay out a still greater part of his earnings for his shelter, or else must put up with poorer and meaner quarters.
