Mike Donatello - Once again, we are creating an organizational paradigm dependent on centralization and unfortunately OIL, as well as removing opportunity for decentralized small businesses. So Amazon is efficient, but at what cost?  Cost of jobs?  Businesses?  I agree much of the failure of small business is inability to compete with a mega-business, but if this is our only solutions, what happens if their centralized business is stopped, hacked, or impacted by oil or other issues?   We let our manufacturing disappear.  Now we are allowing small retail business to disappear.  What are the social consequences for this in America?  In our blind quest for "efficiency" at any cost, what do we continue do to the security of the nation, and what are the soft costs of the social consequences of "efficiency at any price"?
