Owen J. Roberts, Stewart Dry Goods Company v. Lewis…
“ We are told that the gross sales tax in question is in truth a rough and ready method of taxing gains under the guise of taxing sales; that it is less complicated and more convenient of administration than an income tax; and Kentucky for these reasons is at liberty to choose this form, and to ignore the consequent inequalities of burden in the interest of ease of administration. The argument is in essence that it is difficult to be just and easy to be arbitrary. If the commonwealth desires to tax incomes, it must take the trouble equitably to distribute the burden of the impost. ”
