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.
Can a city have the means to do this or would it have to be national?
I don't think a city can do this with Walmart given its size, but many cities have municipal ownership of utilities.
Yeah that makes sense. So something like an ISP would be feasible though. Maybe not Comcast, but one of the local one’s.
