Wow, i can't believe they are actually meeting to develop a world wide currency. This is such an awful idea. This means that if the world wide currency fails, the world as a whole sinks into poverty, and this new system will fail.
As we've seen time and time again in the past, centralized government run banking systems just don't work. They fail every single time (as we are seeing in the U.S. dollar right now with the federal reserve system failing).
So basically this world wide currency will probably work for about 30 years or so and then tank like our current system and so many similar systems in the past.
It's time we returned to some standard not based on stocks and other such things who's value are incredibly subjective. A good thing would be to use something such as a gold standard or this sort of thing. Throughout history gold has maintained it's status as a valuable commodity, so it would work best probably. There would still be fluctuation, but it would be based on the value of gold, which tends to only go up, not down. And at this point most of the gold the world has has been found and mined or is currently being mined, so there isn't likely to be a huge influx of gold into the market to drive the price down, so again it would work well with minimal fluctuation.
And most of all we can't tie every country on the planet to one currency. This has disaster written all over it. I mean, if a single government with it's smaller relatively unified goals can't manage to make a central government run banking system backing their currency work, how is a global consortium of nations going to be able to do it?
This is idiotic governing at it's core.
