"...inevitable but not imminent" yes, exactly and that's the part that the doomsday stackers either forget or conveniently suppress for whatever reason they do (often personal gain). Inevitable may actually mean 100 years or more from now....no one knows for sure. I, like the author of the video, believe that it's good economically to have some diversity in where your money is placed. The obvious rule for investing that I have learned is to try to stay ahead of the bubbles and move your money around if possible and feasible.
I don't think the world is going to keep lending the USA money for another 100 years. I don't know when the Endgame will come but it will.... and when it does, it will be swift and no one will have seen it coming. http://fourthcurrency.com/
