Mahlon Pitney, Shaffer v. Carter — Opinion of the Court
“ That the state, from whose laws property and business and industry derive the protection and security without which production and gainful occupation would be impossible, is debarred from exacting a share of those gains in the form of income taxes for the support of the government, is a proposition so wholly inconsistent with fundamental principles as to be refuted by its mere statement. That it may tax the land but not the crop, the tree but not the fruit, the mine or well but not the product, the business but not the profit derived from it, is wholly inadmissible. ”
