I admit I did not watch the videos, so I apologize if this was mentioned in there somewhere....
Budgets are based, at last partially, on assumptions about the overall economic forecast.
All these budget cuts, and expectations of contributions to be received, and so on....
Are they expecting the world's economic growth to continue as it has been for the past decade or so?
Since the 2008 economic crisis, we've had nearly a decade of great, nearly uninterrupted, growth.
We are overdue for at the very least a significant correction. Quite possibly a major recession, potentially a big one.
What happens if, say, we get a recession that is even just 50%, or 25%, as bad as 2008?
What if their expected income from real estate sales fails to meet expectations? What if contributions fall significantly?
They have all these plans, and budgets, and expected income and expenses....what if, economically, things go pear-shaped far beyond whatever assumptions they have made?
Maybe that is the key to "decline" vs. "collapse".
