Well it would, wouldn't it?!
I'm not claiming for one moment that things like Coronavirus, global warming, the Y2K bug or any other 'emergency' you care to mention don't have some basis in fact. Of course they do.
But you would need to be naïve in the extreme not to see that these things are also exploited and often exaggerated by those who quickly spot an opportunity to make a lot of money from them in a whole variety of ways, be that private companies seeking to make a fast buck or public organisations seeking to justify an increased need for taxpayer funding to 'solve' the problem. Both have a vested interest in creating as much hype and fear as possible, as indeed do journalists in the modern day 24-hour news culture where there is a constant need to for big stories to keep them in jobs.
That's not so much a conspiracy. More a recognition of basic human nature, be that a good or bad thing.
