Australia.
Worlds best LEGALISED brothels/high class escort system. Growing your own pot is decriminalised. We speak English. Lots of hot girls from all over the place with nice attitudes (some would disagree - suckers). World class casinos in every city. Beautiful weather in most places. No Guns. Plenty of gold under the ground so if the world goes belly up - aussie dollars are ok. No nukes anywhere. Population of New York State (20mill.) in a country the size of continental USA - so if there is a world wide famine, there are few mouths to feed and there is plenty of wheat to go around. As an Island - nobody gets here without crossing shark infested waters. In case of a global nuclear war - Australia is the most far away place you could go to to survive the fallout (apart from fiji - but they can get drowned in water if a pole shift hits and melts the ice-caps). Worlds best cradle to grave social security and medicare system (Hence low crime). No "real" mafiosos like in Russia or USA to get on your case. No death penalty so as a citizen you can live with a clean consciousness in knowing that you are not butchering your fellow man. No diseases like Mad cow/foot and mouth bird flu is coming anywhere near here. Excellent new pre-nup laws if you want to get married here. Laid back lifestyle. Beautiful beaches. Similar taxes to the U.S.. Best time zone to trade fx. (and hence manage your own money) OR you can stick your money in aussie govt bonds and collect 6% and have no worries mate.
