“Nothing is more difficult than to equalize the action of the government in reference to the various and diversified interests of the community; and nothing more easy than to pervert its powers into instruments to aggrandize and enrich one or more interests by oppressing and impoverishing the others; and this, too, under the operation of laws couched in general terms—and which, on their face, appear fair and equal. Nor is this the case in some particular communities only. It is so in all—the small and the great, the poor and the rich—irrespective of pursuits, productions, or degrees of civilization; with, however, this difference, that the more extensive and populous the country, the more diversified the condition and pursuits of its population; and the richer, more luxurious, and dissimilar the people, the more difficult is it to equalize the action of the government, and the more easy for one portion of the community to pervert its powers to oppress and plunder the other.”
