When I first learned there was a thing called money, I soon realized I could exchange it for candy and toys. My allowance was in dollars. Everything I desired was denominated in dollars. My paper route customers paid me in dollars. Later, my paycheck was denominated in dollars, my expenses were in dollars, so were the value of my possessions—both assets and debts. My small business, my equity in the house, my mortgage, my car loan, dinner at the Mexican restaurant, groceries, vacations—they are all denominated in dollars. How can I ever escape?
