"The luxury of today is the necessity of tomorrow. Every advance first comes into being as the luxury of a few rich people, only to become, after a time, an indispensable necessity taken for granted by everyone. Luxury consumption provides industry with the stimulus to discover and introduce new, things. It is one of the dynamic factors in our economy. To it we owe the progressive innovations by which the standard of living of all strata of the population has been gradually raised."
