"It's time to abolish all income taxes in America, at the federal and state levels, and declare April 15th to be just another fine spring day."
-- Tom Hoefling
"Imposts, excises, and, in general, all duties upon articles of consumption, may be compared to a fluid, which will, in time, find its level with the means of paying them. The amount to be contributed by each citizen will in a degree be at his own option, and can be regulated by an attention to his resources. The rich may be extravagant, the poor can be frugal; and private oppression may always be avoided by a judicious selection of objects proper for such impositions. If inequalities should arise in some States from duties on particular objects, these will, in all probability, be counterbalanced by proportional inequalities in other States, from the duties on other objects. In the course of time and things, an equilibrium, as far as it is attainable in so complicated a subject, will be established everywhere. Or, if inequalities should still exist, they would neither be so great in their degree, so uniform in their operation, nor so odious in their appearance, as those which would necessarily spring from quotas, upon any scale that can possibly be devised.
It is a signal advantage of taxes on articles of consumption, that they contain in their own nature a security against excess. They prescribe their own limit; which cannot be exceeded without defeating the end proposed, that is, an extension of the revenue. When applied to this object, the saying is as just as it is witty, that, "in political arithmetic, two and two do not always make four." If duties are too high, they lessen the consumption; the collection is eluded; and the product to the treasury is not so great as when they are confined within proper and moderate bounds. This forms a complete barrier against any material oppression of the citizens by taxes of this class, and is itself a natural limitation of the power of imposing them."
