text: why can't each country print it's own money? don't say inflation and bla bla bla!?   don't they? if you're talking about countries that use the euro, it's beacause in such a tightly packed continent with consumers readily traversing country borders, the plan was to adopt a universal currency and do away with conversion rates. if you're talking about countries that use american dollars, well that's because america is the largest economic power in the world and us currency is taken most everywhere.
