Walmart is the largest private-sector employer in the United States, and it’s an important source of low-cost groceries for consumers around the country. It also pays poverty wages, busts unions, and drives economic inequality. Luckily, there is an economically viable route to solving those ills: bring the megacorporation under public ownership.
I was going to say Amazon first! There are so many online stores, and stores that sell online that have to compete with Amazon. Or they can sell on Amazon directly, but Amazon takes a cut. If it was nationalized, selling on Amazon could just become the standard way for stores to sell online. That could be a good thing, as fees could go away or go to the government to run the program better. And there could be some nice service benefits of standardizing the way stuff is sold online.
