The only thing standing in between tech juggernauts and a $1 trillion valuation

Scott Galloway, a marketing professor at NYU and author of the new book "The Four: The Hidden DNA of Amazon, Apple, Facebook, and Google," talks about those four companies. He says the only thing standing between them and $1 trillion valuations is government intervention. He thinks that the most likely source of government intervention will come from Europe, predicting that huge fines will start to come out of the European Union, which he says is fed up with the companies and doesn't have much downside to putting pressure on them.
