Don't most municipalities charge lower / no-sales tax on essentials such as groceries, and higher sales tax on retail, alcohol sales, and restaurants, presumably things lower income people wouldn't be spending much on anyways? I know my state does not charge sales tax on groceries, and limits local municipalities to a maximum of 2%, but I admittedly don't know what the norm is in most states.
