Pennies
During the Super Bowl, Trump decided that the U.S. Mint will no longer make pennies. When banks run out of pennies and businesses cannot get enough pennies to make change, what should happen? Should the business round up the change in the customer's favor, or should the business round down the change in the business' favor?
It's not as if eliminating the minting of pennies will eliminate cents in commercial transactions. Even if businesses set their prices in multiples of a nickel, they will still be required to collect and remit sales taxes to the nearest cent.
It reminds me of that time in Superman 3 when Richard Pryor figured out how to program a computer to steal all the rounded cents and add them to Pryor's paycheck, a scheme which of course culminated in a supercomputer that tried to take over the world.
In the world I see, you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Tower. And when you look down, you'll see tiny figures pounding corn, laying strips of venison on the empty carpool lane of some abandoned superhighway.
