A good and accurate education about money is lacking for most people in the USA, I love when I cash a check at the bank and the teller will ask,"how would like that back?" I tell the in U S dollars. Then when they give me Federal Reserve notes I say "it seems you have made a mistake, I asked for U S dollars." They have no clue, so I explain that if they are going to work in a financial establishment like a bank it would serve them well to learn the difference between dollars and notes.
