I think the argument is, their is no way ma and pa can compete, since the market they are dealing with is so much smaller. I can see how a smaller town would want to keep out walmart. Less full time jobs, less money, etc. Although, lets be realistic. Is ma and pa providing healcare for their 6 employees? I doubt it. People can get their own insurance, they can save for medical emergencies, etc. But why do that when the state will pay for it right? The fact that people are lazy and lack forward thinking, doesnt mean Walmart is evil, it means people are dumb.
