Bottom line the Tower has buckets of money and they're streamlining. They have staying power from that respect but I can see a time where they're a shell of what they once were much like Scientology has become.
This could be a sticky for the summation of the Borg.
There is a definite feel of, if not desperation, then urgency, in their cutbacks of Branches, Bethelites, Missionaries, Specials, older CO's, DO's, as well as the scraping of every congos' last nickel, insane Circuit Assembly expenses, right-sizing of KH's, video-begging, scrapping of recent releases, and 16-page bi-monthly rags.
The real numbers guys inside the Borg know what is happening, and it is not pretty.
