Well, pandemic is not like the other crashes as you can see but there is really no point on arguing since it is kinda the same thing in the result so how it happened doesn't really matter. If you check the previous reasons why there was a crash it is all financial related and they all caused financial problems for the nation or the world sometimes, if you go waaay back before 90's you will see that there was ton more of those crashes and it was still mostly financial related as well.
The difference right now is the fact that there was a pandemic that caused people to stay at home as much as they can, which obviously has financial results but the reasoning are difference, it is health related reason why the crash happened so it is not the same, however the result is the same so there is really no point arguing about it.
Oh, it is very important to know the true cause of the pandemic, don't you think? Man-made (deliberate), man-made (accidental), or natural.
I would agree financial crises as such are more frequent than financial crises caused by other types of events. However it is possible to find examples of deliberate deflating of financial bubbles to prevent a crisis. Immediately coming to mind is the mid-80s actions by key US figures to 'talk down' the dollar, when the dollar was considered over-valued and in a bubble. Then when the dollar dropped too quickly, forcing the Europeans to cheapen their own currencies to help stop the dollar's decline. The result (the Plaza and Louvre accords) has been considered by mainstream economists as one of the most successful examples of recent policy making.
Another big example of preemptive stabilization was creating the 'international gold standard.' After suffering one financial crisis every ten years or so in the early- to mid-19th century at home, the British Empire decided to push all major silver and gold-silver countries (France, Germany, US, other European countries) to adopt the gold standard and stop using silver as money. Since Britain had been the only major gold-only country, this immediately increased her wealth against her commercial competitors, as the price of silver collapsed. Even more importantly, with bank and central-bank co-ordination among the major countries, this effectively used the real economic power of all the major countries to support the value of British-issued paper assets. The result was decades of 'peace and prosperity' in Europe and N. America, until 1914.
So it is possible, at certain times, for the global elites not to wait for a financial crisis to occur, but proactively defuse it and stabilize the system preemptively.
