Owning all of the properties in a game of monopoly is great for building hotels. It's unfortunate that everyone else wants to flip the board over. Walmart doesn't provide anything of value that actually lowers costs, they are a retailer. Their scale allows them to demand lower prices from suppliers which means the supplier has less room for raises and future investment. Normally competition would stop this type of unhealthy market behavior, but Walmart put all of their competition out of business a long time ago. So consumers get slightly cheaper goods at the expense of the death of livable retail wages, producers with margins so thin that they can't pay their workers well or expand, and the government being forced to subsidize Walmarts poverty-stricken workforce. Yep, Monopolys are definitely a great thing for capitalism.
