According to the IMF, World GDP in nominal terms expressed in dollars was $57 trillion in 2009. The European Union accounted for 29% of that; and let's say another 10% of the world implicitly or explicitly link their currencies to the euro (for the sake of argument I’m assuming the pound tracks the euro and the yen will track the dollar more or less).
Regardless of what the Gold-Bugs say (and they may have their day in court yet), the rest of the world effectively uses dollars. So…if the euro in 2010 on average (or however the IMF works it out) is worth 75% in dollar terms, compared to what it was in 2009, and assuming anaemic growth, rough number that would mean World GDP in nominal terms denominated in dollars would go down by 39% x 0.2 = 8%.
Rough Numbers!! Of course that’s not “Real.” And it does not account for PPP or any of those clever benchmarks that economists use to pontificate about this or that and justify their existence. But dollars are dollars, and nominal GDP is simply about dollars or their equivalent, passing from one pocket to another.
And then the penny dropped that “someone else” would NOT be happy to lend money to profligate PIIGS and the like so that they could pay huge sums of money (that they don’t stand a chance in collecting in taxes), to pay for armies of public servants and union members to live a life a of luxury, at the expense of a diminishing pool of people who actually work for a living and pay the part of the wages and pensions of the “majority”.
The trick there was that the majority always vote for an easy life of play-today pay-tomorrow, that’s what democracy as it is currently practiced is all about, that’s why UK joined with America to invade Iraq, it was the “will of the majority”. Just like the majority of Americans (the 70% who owned houses), voted for the housing bubble (and what they are really angry about is it burst).
That’s the joy of democracy, when nations vote to commit collective suicide (and there is a lot of pork to grease the wheels (no pun intended)), well if they have a majority, that’s what they will do (witness the credit crunch).
Put it another way, if the “profits” that banks reported in 2006 and…
