What makes things precious? For example Gold, Silver, Diamonds, etc. Once they were unknown to human being. And now they are the more pricey things.
I guess its just the way these things were marketed into the world, Demand and Supply control makes them pricey, there are a lot of other metals too in the world, which are more expensive then gold, but they are not that much poplar or in demand.
Similarly if we look into brands, Gucci, Armani, Micheal Kors, etc. Once they were unknown, no one knew about them. But now, they are the most expensive brands in the market.
I know in brands companies cash their name, that's why they are too pricey. But my concern is what exactly makes things precious and pricey.
