David Ricardo,
On The Principles of Political Economy…
“ M. Say says, that "the tax, added to the price of a commodity, raises its price. Every increase in the price of a commodity, necessarily reduces the number of those who are able to purchase it, or at least the quantity they will consume of it." This is by no means a necessary consequence. I do not believe, that if bread were taxed, the consumption of bread would be diminished, more than if cloth, wine, or soap, were taxed. ”
