That would do, why don't you go to every store that every chain has and figure the national average price on everything, then ignore the wages that their employees make (to be spent at the other business in town, maybe even funding your job), and draw up an addition to the article determining who benefits from shopping where. Let's say Company X has a store, with 500 jobs, paying $10 an hour, then Company W comes in,  adds 500 jobs, paying $6 an hour, drives Company X under, now the wages that Company W pays are the ones being spent in the area, guess everyone benefits from a 40% drop in the spending from 500 people's incomes.
