Amazon is following Walmart playbook. This is what Walmart did to make sure timely (Just-in-Time) Delivery between their warehouse and retail locations. There are business case study on how Walmart used their own freight truck network to beat their retail rivals by dedicating more space in a retail store to retail shelves instead of storing inventory.
Precisely. Later, they simply leased the space out to corporations like P&G (or their subs ) and offered logistics/freight service. WalMart was the first retail network to roll up the whole day every day into a single ( green-bar) report on Mr. Sam's desk.
Walmart built up their massive infrastructure business while being simultaneously immensely profitable. However, at Amazon, building out infrastructure comes at the expense of profits.
What am I missing that a lot of smart people are seeing in Amazon?
