We could then classify the exporting of Dollars as the 2nd most profitable "business" [0] "Last year, the United States exported $65.3 billion of its currency — mostly $100 bills." "Printing dollars, after all, is a very profitable business. Ranked by value, greenbacks finished second on the list of America’s most valuable export products, just behind refined petroleum. But exporting money is much more profitable. It costs the federal government around 14 cents to produce a $100 bill, and a few more cents to send it overseas. In exchange for each of those bills, the United States gets an interest-free loan of $100. At the end of 2018, foreign holdings of American currency totaled $773.9 billion."
