There are two towns on a hill called High and Low for their respective position on the hill. While High’s merchants can send goods for free to Low (as it’s downhill all the way), Low’s merchants have to pay dearly to ship goods up to High. One day the merchants of Low get together and proclaim that they want “a level playing field” because it is “unfair” that High’s merchants ship for free. So, in the interest of

“fair trade,” Low requires all merchants from High to take their goods down the hill, then back up, and then back down. Are the people of Low better or worse off now that trade is “fair”?
