What I gather from these posts is that in the "old days" -- perhaps prior to 1979 or 1980 -- a priority was placed on Staff auditing, and sufficient time and resources were devoted to the auditing of staff.
It appears that after 1979 or 1980 this changed, and neither sufficient time nor sufficient resources were were devoted to the auditing of staff.
There is a possible explanation for this change in behavior that may,
or may not, be valid.
The explanation would be that after years and years of investing time and resources in the auditing of staff -- of, as I put it earlier,
eating their own dog food -- the "powers that be" (Int., Exec. Strata, etc.) learned that it was
not cost effective. That they learned, after long experience, that auditing staff was not worth the time, effort and investment involved.
That they learned, after long experience, that auditing did not create superior beings -- or at least beings who were sufficiently superior to mere "wogs" to justify even allowing staff to co-audit, or even allow staff to serve as pcs for student auditors.
When the choice came down to having a staff member say, stuff envelopes, versus co-auditing or serving as a pc for a student auditor, the decision was made that it was more economically beneficial to have the staff member stuff envelopes.
In other words, the "powers that be" (Int., Exec. Strata, etc.) learned after long experience that auditing was not worth much, really, at all.
But at the same time the "powers that be" (Int., Exec. Strata, etc.) continued to tell the public that auditing was so beneficial that people should max out their credit cards, mortgage their homes, and take time off from
their jobs to go to Flag.
Seriously, how can the Church of Scientology, indeed how can anyone, assert that auditing makes people more effective, and more than pays for itself in the long run, when it is not worth time away from stuffing envelopes, doing call in, or standing in front of an OCA table?
