As an example of that theory in action. Rupert Murdoch bought Fox broadcasting and both makes money from in and puts forth his personal ideology. Arguably he might have made more money with other investments, but it's been a vary solid investment. Monsanto is not just a major agricultural company they actively lobby for stronger patents. At a more pervasive level 'Climate Change' is not just science it's become a political debate with well moneyed people and organisations actively trying to influence things.
