Ramil you are talking about Bretton Woods, right? And how the US started having money that was backed up by NOTHING.... And then others started following suit. Surely Crocodile knows about this! I can't believe how anyone could think it's a good idea for one country to be able to run the rest of the world off it's own currency, which additionally is backed by nothing, allowing them to create more value out of thin air, simply by printing more money.
Unless you are a citizen of that country, of course.
