$2trn (That's two trillion dollars) of the combined worth of planet Earth's billionaires has disappeared over the past year.
(Across the globe, the number of those who can boast a fortune of over a thousand million US dollars has shrivelled from 1,125 to 793. The 10 biggest dollar-losers between them have this year lost more than the annual GDP (gross domestic product) of Ireland. Of course for those of us who are struggling to hold onto our jobs, or our houses, this is barely on our radar.)
