Power = Control of the flow of capital and the flow of information.
The pen is mightier than the sword, precisely because if you can get people to side with you, then you can get an indefinite number of swords.
Controlling that which people think is right and true is real power. To do that you have to control the flow of information. i.e. you have to control the media. It takes a lot of money to control the media. To get that money you have to control the flow of capital.
