Rich people prepare the future life of the poor?

From Fernand Braudel, The Structures of Everyday Life, p. 184:

Luxury does not only represent rarity and vanity, but also social success, fascination, the dream that one day becomes reality for the poor and in so doing immediately loses its old glamour. Not that long ago a medical historian wrote: 'When a food that has been rare and long desired finally arrives within reach of the masses, consumption rises sharply, as if a long-repressed appetite had exploded. Once popularised [in both senses of the word - becoming "less exclusive" and "more widespread"] the food quickly loses its attraction... The appetite becomes sated.' The rich are thus doomed to prepare the future life of the poor. It is, after all, their justification: they try out the pleasures that the masses will sooner or later grasp.
