I think Walmart is a bad example because there are thousands of giant stores across the United States full of employees. I think most people assume they also do their own distribution/fulfillment shipping of goods to their stores and customers, which requires warehouses also full of employees.

eBay doesn't do fulfillment, or payment processing, or really anything other than running the website/mobile apps/api, customer service, marketing, etc. There has to be a lot of waste there.
