She didn't really say there did she? I have seen it in the paper and now I hear she said it again yesterday. No one really thinks this is possible, do they?
To be clear, everyone is completing with everyone else. Tom's Place is competing with Mary's, that is completing with Quatro's, that is completing with Papa Aldo's, that is completing with cans of spaghetti in the grocery stores. You aren't going to stop Lowes, Staples, Walmart, Best Buy, Barnes and Noble and Krogers, from competing with the Coop, Shawnee Trails, B&L Photo, Rosetta News and True Value. That is the way the USA works.
Further, the citizens of the USA like the big box stores. They are generally well run, have lots of merchandise, and low prices. There is a reasonable argument that the low prices in the big boxes (and in particular Walmart's low pricing of Chinese made goods) are driving the efficiency of our whole economic system.
Could someone explain how Sheila plans to keep the big boxes from competing with the locally owned small businesses. If you can't explain it, we will have to put this down as another one of Sheila's silly ideas. IMHO, stopping a fair and open market can't be done legally and would be a bad idea if it could.
