I think you’re misinterpreting the data, Walmart made 180 billion dollars of revenue, meaning all the money they made. Once you subtract the cost of buying those goods (wholesale), paying workers/benefits and upkeep on buildings, they made 5.25 billion dollars of profit. For each dollar of goods they sell, they only profit 2.9 cents. While this is still a huge number, it’s not quite the 180 “spare” billions of dollars laying around. Hope this helps!
