What still further exacerbates the feeling of injury on the part of those whose interests are proscribed, is the fact that the purity of motives of the persons most active in the campaign of proscription is not always clear. Not many years ago we had a thriving manufacture of artificial butter. The persons engaged in the industry claimed that their product was as wholesome as that produced according to the time-honored process, and that its cheapness promised an important advance in the adequate provisioning of the people. We destroyed the industry, very largely because of our strong bent toward conservatism in all matters pertaining to the table. But among the influences that were most active in taxing artificial butter out of existence, was the competing dairymen's interest. It is asserted by those who would shift the whole burden of taxation onto land that they are animated by the most unselfish motives, whereas their opponents are defending their selfish interests alone. Yet a common Single Tax appeal to the large manufacturer and the small house-owner takes the form of a computation demonstrating that those classes would gain more through the reduction in the burden on improvements than they would lose through increase in burden on the land. Let it be granted that personal advantage is not incompatible with purity of motives. The association of ideas does not, however, inspire confidence, especially in the breasts of those whose interests are threatened. Extinction of property interests without compensation necessarily makes our legislative bodies the battleground of conflicting interests. Honest motives are combined with crooked ones in the attack upon an interest; crooked and honest motives combine in its defense. Out of the disorder issues a legislative determination that may be in the public interest or may be prejudicial to it. And most likely the law is inadequately supported by machinery of enforcement: it is effective in controlling the scrupulous; to the unscrupulous it is mere paper. In many instances its net effect is only to increase the risks connected with the conduct of a business.
