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.
Literally, just nationalize all providers of basic goods. Water, power, telecoms, grocery stores, housing, and hospitals. We can keep some private brands but we control the way they interact with consumers.
