If you’re not reading the Economist’s Graphic Detail blog, you should be. Thursday, for instance, they posted this gem:

The striking takeaway from this graphic is that Facebook has approximately one-tenth the employees of Google. Compare that with their valuation, which is more than half as large, and their monthly user base, which is also more than half as large. And Google, of course, only has one-fiftieth the employees of McDonald’s.

Which raises a question I’d love to know the answer to: Has any major company — let’s say with a valuation of $50 billion or higher in today’s dollars — ever had a lower ratio of employees to customers than Facebook does?
