It is much more efficient these days. They use apps to determine when to stock, how much to stock ect. They need many fewer people, and they run much leaner. L

It is much more efficient these days. They use apps to determine when to stock, how much to stock ect. They need many fewer people, and they run much leaner. Like I mentioned in a comment above, who we consider made it happen is arbitrary. Walmart cannot exist without a functioning society. The daughter of Sam Walton never worked at Walmart, yet she gets more of that gain than any other individual. For other products, it is even more arbitrary who gets the benefits. If facebook disappeared, another company would quickly take the role of social media leader. Likely not much would change from a productivity standpoint. Yet whoever happens to get the role of dominant social media ceo makes billions.
