Amazon has 24,000 workers in Seattle and is building office space for 70,000 more. Why? * Are they relocating 70,000 workers from other areas? What areas? Why would they relocate these workers? * Are they adding 70,000 new jobs? It's possible that Amazon is planning to expand. I have no idea. * Are they building office space without intending on using it? Amazon would have to have a very good reason for doing this. Maybe they plan on starting up a lot of business units and doing a lot of churn-y startup-y things? Maybe they plan on renting it out? Maybe they're just sinking money into Real Estate to retain their no-profit image?
