I often wonder what would it be like if there was only one currency in all the world say a 'Globo'. The advantage I can apparently perceive is a global harmony at least in the currency field, savings on transactions into different currencies, the ease of comparison of different economies eg the price of a watermelon in Pakistan is 30 cents while in japan it is 20 dollars. We never readily realise the dichotomy of world economics because of differing values of individual currencies. A single currency would be easy to handle, to compare, to transact etc. I don't see any disadvantages. If I'm missing out on knowledge base, can any one educate me please.
