Q: What is the General Economic Situation of the planet?
(A) In Canada, there isn't much of a Society for an Economy to form around. In what's left of The United States, the Barter System reigns supreme, but there are a few recognized currencies in some areas, Trade is somewhat hazardous due to Banditry, Erratic Weather, and Radiation. In South America, the Cactus Conflict, and the Farming Turf Wars have stunted Trade somewhat, but a few small City-States manage to Trade to all of the Factions extensively, Merchants are, by and large, allowed free passage throughout the Region, as their goods are essential. In Europe, there is almost no Trade between the Duchies and the Fascists, but the Duchies Trade very extensively with one another between Feuds, and rarely, European Merchants travel and do Business abroad, for a large, if extremely dangerous profit margin. Many seperate Coin currencies are acknowledged in Europe but elsewhere, aren't as valuable. In Africa Trade is almost entirely centered on the Coasts, and mainly involves the Exchange of Optimized Animals and Natural Resources for Advanced Technology. In The Tech East, the Economy is Prospering, and The Japanese Yen is one of the most valued currencies. In Russia, Trade between Vaults and Settlements is frequent, and Alcoholic Beverages are used as a medium of Trade, but Firearms, Ammunition, and Food, are all highly valuable there. Extensive Piracy, Belligerent Giant Jellyfish and Sea Mollusks, Dangerous Storms, and the Expense of Fuel all hinder Oversea Travel, making Transcontinental Trade somewhat rare, though not unheard of in Coastal Cities.
