That merger isn't going to happen – at least not as it is proposed now. The union has already squashed it, and I'm sure when the government gets involved, they aren't going to allow it either.Walmart is not even close to a monopoly. A lot of people shop at Target, other retailers, and Amazon. Kroger will soon be a big competitor when they aquire Albertsons, they will have almost as many stores as Wal-mart.
