On. Yu. Mamedov. Modern economics (№ 464134)

Expensive goods are bought precisely because they are consistently expensive, and the benefit that the buyer receives is the hope of a win-win investment in money savings (for example, the purchase of gold, jewelry, furs, land, houses, apartments, paintings, items of applied art, rarities ). And since they are consistently expensive, i.e. the price of these goods tends to increase, then there is still the same hope - to profit from tomorrow's prices.
