The OP makes some very good points. The more notable and worth close scrutiny are the project management, the internet, and education;
Project management - clearly the org tried using in-house engineers, architects, project managers, foreman's, etc. What they fail to realize is if these imbeciles DO NOT HAVE ANY REAL WORLD EXPERIENCE ASIDE FROM BASIC SCHOOLING, they have gambled BIG and lost. Their imbecilic thinking have cost them millions in initiating, planning, executing, monitor and control, and closing (basic tenets of project management). I can tell you that if the first two phases of PM were done incongruously, I can certainly see the money bleeding.
The internet - the proliferation of the internet TODAY exposing what the organization truly is can only be detrimental and will continue for many more years to come. The current, ex, and non-members that have come forward to propagate the Truth as it should be, are applauded and have done a loving service to their listeners and audience. It is a shocking day when a faithful Christian witness has to secretly and covertly view information critical of the organization yet truthful in all regards.
No Education - this is perhaps one of the more damning teachings that continues to reverberate today and will continue to do so many more years into the future. Can brothers who have family's in city's like Los Angeles, New York, Miami, Chicago, and other major metropolitan areas truly afford NOT TO BE EDUCATED? Can they sustain their families AND contribute to the organization every month? Today more so with the new arrangement.
I can only surmise that the WTS is now receiving divine justice and it will only accelerate as the months and years go by until the GB realizes their troubles are not of human origin or their stupidities but rather from Jehovah who said himself he would start the cleansing of his people with his people being first in line. If not, how does one explain these troubles without God putting a stop to it?
