Richard Daughty (the Mogambo Guru) refers to articles by Nouriel Roubini and Sharon Kayser, giving us debt -threat vistas of $1 trillion and $1,000 trillion respectively. Then he returns to Terry Pratchett's Discworld dwarves' favourite song ("Gold, gold, gold, gold...").
Two problems: one is, I can't visualise anything with many zeroes, so it's not real for me. More importantly, if there's a major meteor-strike financial bust (i.e. deflation), I'd have thought cash in hand is what everyone will want.
Unless a crazed government opts for hyperinflation. In which case, I'd rather have pallets of canned baked beans, boxes of ammunition and many brave, loyal friends. You can't eat gold.
But as with all truly terrible imaginings, the mind bounces off this like a tennis ball from a granite boulder, and we turn back to normal life with determined optimism.
