The answer is very complex. I could write a book on this.
If you want my honest answer/guess in a concise way....
First you have to understand that
- Corporate Capitalism is a machine which has been created by humans. The sole function of this machine is to concentrate wealth into the hands of those who already have wealth.
- Every profit-making venture works by "Enclosure" of a Common good, which is a resource which is either desirable, or necessary for life. This involves putting a fence around it with a lock to keep the people OUT, then leasing or selling the good to the people. See: http://en.wikipedia.org/wiki/Enclosure. Our corporate-commercial for-profit media work just like this.
- Capitalism, with it's rules of unrestrained and perpetual growth, cannot co-exist with any other competing system. It must utterly destroy and silence all competing systems.
- Capitalism/Property cannot coexist with Democracy, because Democracy is based on egalitarianism (equal rights for all). Capitalism/Property in a fundamental way, requires Class disparity between the owner (with all the rights) and the dispossessed (without rights).
- Democracy cannot function without an informed population about the truth of our reality.
Once you understand these things, everything begins to make sense.
- This is why the corporations have seized control of mass media.
- This is why nearly all the nationally syndicated radio commentators are radical-right wingers (pro-corporate, pro capitalism, pro-war, anti-environment, anti-peace, anti-life)
- This is why you can't get a radio show or TV show on a local station during prime time, *even if you have the money to pay*!!!
- This is why the big cable companies and telcos want to KILL public access, and keep the people away from the microphone at all costs.
- This is why there is a merger between "Journalism" and Public Relations, both in the academy, and also with a revolving employment door.
- This is why the corporations have "enclosed" our system of elections and lawmaking.
- etc etc etc.
