"Instead of there being a myriad of locally owned and operated businesses there is instead a single business with undue control..."

What hysterial nonsense! Everything else will close eh? Not half, not one tenth, not 1/50th of the businesses in and around town will close because of competition from WalMart. And those that do, were ripping off customers by charging too much when WalMart brings affordable pricing to low-income shoppers, transforming the precious few dollars we have left after paying sky-high gentrified rent, into a Living Wage so that we can live like human beings instead of peasant wage slaves!
You can obsess about "big boxes" but I LIKE MOST REAL PEOPLE will be buying baby food and milk and cleaning supplies and baby clothes and new dishes and new tires to get me to work. Welcome Wally World WE NEED YOU!
