Like any organization, for-profit or otherwise, the WT will adjust to survive. I think they were overextended with too many Bethelites, too many higher cost facilities. There are a few underlying financial-related problems that won't go away:
Declining membership in affluent countries, increasing membership in third world countries; hence lower donations.
Aging and dying core members, who tend to donate more. The religion is less attractive to the younger populace.
Increasing number of lawsuits and expensive settlements.
Their 100+ year old business model; ie print paper literature and sell it; is a thing of the past and won't be coming back.
Financial issues alone won't bring the WT down, maybe something else will, but they will adjust financially.
