You're not making any sense,
All these dire scenarios point to economic disasters, not a means of making piles of money. How could a conspiracy of evil doers hope to profit from a policy that would only make the world bankrupt? Any such alleged conspiracy would be much more likely to hope their meddling would create trillions in wealth, that they could then plunder.
What's much more likely, on the face of it, is that these predictions are scare tactics devised by those who tend to profit from the way things are going now, and who will do anything they can to keep things from changing.
