David Ricardo,
On The Principles of Political Economy…
“ The monopoly price of one period may be much lower or higher than the monopoly price of another, because the competition amongst the purchasers must depend on their wealth, and their tastes and caprices. Those peculiar wines, which are produced in very limited quantity, and those works of art, which from their excellence or rarity, have acquired a fanciful value, will be exchanged for a very different quantity of the produce of ordinary labour, according as the society is rich or poor, as it possesses an abundance or scarcity of such produce, or as it may be in a rude or polished state. ”
