If you were to wake up tomorrow and found out that money, jewelry, and precious metals (gold) and gems (diamond) are worthless, which group of people will most likely go insane first? Those so-called respectable middle class who always stress on hard work and savings or the wealthy ruling elite who (used to) have most of the money and control most of the wealth? And why?
Of course, the working class and the poor would probably just laugh and think it's funny.
