Money has such a large role in society that not much gets done without it. Often, money cannot be seen physically, although valuable in many ways. Total faith must be placed in the government and banking system to assure everyone’s money is being handled in the proper manner; if not, then paper notes would be hiding under mattresses across America. Most ordinary citizens are in the dark about what happens behind the scenes in banks. Money is much more complex than either having money or not. That being said, the Yap Fei, the US gold standard, French francs, Brazilian cruzeros and debit accounts are examples of money not being physically seen. Nobody is handed cash at the end of the week, just a number added to an online banking statement; this is where the faith in the banking system comes into play.
