Thanks I’ll look those up.
I always thought Black Swans were unexpected events.
Those all have reasonable expectations.
Let me add;
Major earthquake (like Japan recently), causing nuclear power plant issues.
This would cripple our already dicey economy.
About the EMP vs ouside hacking; although our power grid could be taken down for a period of time by “bad guys” it would never have the same results as an EMP. (Read the book One Second After). Even the Russians have long known that, if you only have one nuke the best use for it is an EMP.
Here’s the blurb and way to order “Biflationary Depression” on Amazon’s printer. It is cutting edge. https://www.createspace.com/3683488
