Amazon makes money because they don't pay their taxes and they don't pay full price on shipping.  Uber in even worse.  It is a loss-making company that has no way to cut prices because as it turns out, changing from calling a cab with your phone to using your phone to call a cab and watch it arrive on your phone doesn't cut prices.

What taxes, exactly, is amazon not paying? 
  
 And what, is amazon supposed to not try and negotiate a favorable price due to their volume of shipping? Literally every company ever with large volumes negotiates and gets a better price.
