A significant factor is loss or doubt of credibility of all senior personnel leading the system. Too many situations are arising where if nobody is getting kickbacks or bribes, it's probably only a couple of years away before the entire system collapses.
The guilty parties know what they're doing. Another batch of parties orchestrate systems of bureaucracy to cover their empires under the guise of improving efficiency.
Another group implements the policies and directs the funds in consort with partnering and TQM/TQL and improving business practice parlance.
Another group follows their lead and generaly are unwitting dolts just doing their duty without any cognition of ramifications. (Same class of folk who amazingly can walk down a sidewalk without killing themselves in the process.)
Convolute this with contracting out all the processes and you've got an incredible mess. Checks and balances are corrupted thanks to the Clinton legacy. In a nutshell, Corruption.
When I use the term corruption, this isn't the sae as impropriety or theft or graft or illegal activity. It simply means the system is no longer truthfully rendering it's intended function at the appropriate cost. The system has been corrupted. Corruption.
