Communications in the Workplace - NO P.I.E. Tomorrow and Today

If communications is so important why has this be conveyed to the minds of corporate managers and CEO's that have been in there jobs for so long that they have forgotten to effectively communicate with a group or organization. A well run group can get stagnate, because it is running so smoothly there are no meetings with anyone, there are no discussions with anyone. The engineers and team leaders feel like mushrooms who are keep in the dark a great deal, and only told what they need to hear or know. This is very true and disastrous with managers in defense contracting industries.
Many defense projects go over budget, and extremely over the allotted time such as many projects that companies such as Lockheed, BAE Systems, ITT Systems, Raytheon, General Dynamics, amongst the largest. These company have meetings and communications all week long, but many of the upper management doesn't "Listen" to lower management or the engineers who are told to be quiet, and don't complain about anything if they want to keep their jobs. I have been at too many defense contracting companies, and let go as a contractor because I saw flaws in their system due to 20 plus years working at dozens of different companies. I could tell within a week if the company was run well, and treating their employees with dignity and respect. Many employees in today's market are fearful to say anything about anything.
Tomorrow's new business rule as companies will be: NO P.I.E. -- No personal cell Phones, No personal Internet, No Personal Email at work. Already many corporations are implemented this plan, cellphones are being banned because of their abuse. A cellphone today is no longer a simple phone, it is a communications tool, gaming systems, mp3 player, and movie player.
Many bored employees have new areas to waste time at work. Most websites are banned because companies don't trust their employees, or they abuse the privilege of being able to access the internet at lunch. Many companies have url tracking that records what websites everyone in the company goes to and how long they are on every day. I have know many people who were fired due to the fact they didn't think anyone would notice them spending hours a day on the internet looking at sites that some would think improper for the work environment.
Today's Project management books have addressed these areas and why some companies have a gestapo, hardline attitude on these issues.
Many people get bored with their jobs and can't change because of the state of the economy. They are fearful of saying anything at work, so they all Twitter and Facebook to vent their frustrations about not being listened to anymore.

Hey, we have millions of homeless and starving in this country and not the president or anyone running for presidency, or congress has ever addressed a Solution to this growing problem.
