What Cofty said,
As many of us have pointed out on several occasions, the Dark Tower seemed to be having a cash flow problem. The selling and transferring of capital assets appeared healthy to very healthy from what we could see. Corporations and churches typically do not use cash flow/income for capital projects; they are funded by capital transfers, loans, etc.
If the Dark Lords have truly stopped the construction projects and laid off more workers, it strongly suggests that they are having both capital and cash flow problems to the point that day-to-day operations are impacted. Of course we do not know the extent of these, if it is a temporary blip, etc., but the two issues combined appear ominous from a financial standpoint.
As some have already pointed out, starting these projects without the upfront capital makes no sense. If they didn't have it and hoped to get it, they are financial fools. If they had it but now don't, it means something has changed. This could be the pending lawsuits, environmental cleanup costs, lowered credit rating (and thus higher financing costs), bad investments, overages on building costs, etc., or a combination.
The one thing that would bring the Dark Tower to its knees quickly, as previously pointed out, is for the rank and file to stop donating. Their re-engineered business design appears to be completely predicated on donations - they stop, the engine stops.
