Earlier quoted context omitted.
Say you've invented a product and are producing them at a small scale (100 units per month). What would it take to sell that product at Walmart? What would it take to sell it on Amazon?
Amazon sells all products, Walmart only sells some. Amazon sells online, Walmart sells in retail and online. So Amazon might preference another product, while Walmart both preferences other products and doesn't even accept most. Walmart preferences other products online as well. Yet Amazon is a monopoly? So if Amazon greatly restricted their product offering, they are good to go?
I'm not certain why we seem to be debating the merits of Walmart versus Amazon. I would be willing to venture that Warren supports regulations and potential antitrust action against Walmart, too. Just because she's proposed antitrust action on one type of organization doesn't mean she won't also support another - indeed, she wants the same of many organizations on Wall Street, and previously sponsored legislation to regulate Walmart to prevent poor labor practices [0].
