Walmart isn't competing openly though. They have a 100% monopoly on wallmart shelf space. Target is a different platform down the street sure, but that's like Apple vs. Samsung. You can't get the Apple app store on a Samsung, and you can't get the android appstore on an iPhone. But Target can't put products on wallmarts shelves and wallmart can't put products on targets shelves.
If you walk into Walmart, you’re not going to find a Target. And you’re certainly not going to find a Target paying 0% commission to Walmart.
There you go, another equally ridiculous Walmart analogy.
