Pursuit of market share vs pursuit of profit. Amazon seems to want to dominate every market they want to get into. While Walmart focused on dominating one market - retail. I compare Amazon story to Gold Rush. Once Amazon penetrates gold mining business, it wants to move into business of providing tools for gold mining, storage, distribution, and consumption. The profits from the initial gold mining efforts goes into building organizational infrastructure of gold vertical as well as entry into another new vertical.
