“Laws have been passed in one state and another abridging the right of contract, the right to sell merchandise, the right to labor upon public works, the right to labor more than a certain number of hours, the right to freely come and go, the right to pursue legitimate trades, and a mass of others. Some of these laws go directly to the point, but the majority proceed by indirection. Too many succeed in evading the decree of unconstitutionality and bear oppressively on natural rights. The selfish interest of classes ever anxious to push on their own fortunes, reckless of what destruction is wrought to others, is their moving cause. Legislatures, pliantly serviceable to the demands of influential cliques and unchecked by weak-kneed governors, spread them on the statute books, and there they stand, discouraging prophecies of the decadence of popular rights under democracy. They hide in swarms, behind the newly coined phrase, "police power," and that other more venerable phrase, "the public welfare," both of which, like "public policy," are often, if one may use such an expression, liveries of heaven stolen to serve the devil in.”〔Theodore L. Stiles, Legislative Encroachments Upon Private Right, 1899 PROCEEDINGS OF THE WASHINGTON STATE BAR ASSOCIATION 69.〕
