It works like this: Once a month, the debit-card accounts of those receiving what we still call food stamps are credited with a few hundred dollars â about $500 for a family of four, on average â which are immediately converted into a unit of exchange, in this case cases of soda. On the day when accounts are credited, local establishments accepting EBT cards â and all across the Big White Ghetto, âWe Accept Food Stampsâ is the new E pluribus unum â are swamped with locals using their public benefits to buy cases and cases â reports put the number at 30 to 40 cases for some buyers â of soda. Those cases of soda then either go on to another retailer, who buys them at 50 cents on the dollar, in effect laundering those $500 in monthly benefits into $250 in cash â a considerably worse rate than your typical organized-crime money launderer offers â or else they go into the local black-market economy, where they can be used as currency in such ventures as the dealing of unauthorized prescription painkillers â by âpillbillies,â as they are known at the sympathetic establishments in Florida that do so much business with Kentucky and West Virginia that the relevant interstate bus service is nicknamed the âOxyContin Express.â
