The point in question is that it is debatable that a startup like Uber, or Airbnb create absolute wealth: that if airbnb is worth 1billion dollars, they created 1 billion in value, because they also damanged other industries. Facebook can be super successful, but more people use it at work that they used to, is there a negative value effect of its services in society? Are cabbies poorer because of Uber? A huge part of startup growth is effectively eating other industries, something always ommited in the argument "we create value, we are just making the pie bigger". Business are supposed to devour each other, its just a bad image to give.
