As for the business about job losses, President Trump has a point — to an extent. As Amazon has grown, other companies have diminished, particularly big-box retailers like Circuit City, Tower Records or Borders bookstores, all now gone. Amazon isn't the only successful Internet competitor (and Internet competition isn't the only factor shaking up the sector), but it's the 800-pound gorilla of retailers. Retailing jobs aren't being lost so much as shifted by competition. Amazon is hiring. Best Buy has been downsizing. And, of course, if Mr. Trump is going to complain about Amazon's expansion, he probably ought to stop bragging about whatever portion of the U.S. job expansion Amazon has provided since January.
