Interestingly enough, I think the USA would be one of the countries that could actually come out ahead. There's one good reason for this: if necessary, we could tap into the gigantic mountain of resources to keep the country going. Economic self-sufficiency, as economic doomsayer Gerald Celente noted, will be the order of the day. It should be noted that the USA can use NAFTA connections with Canada and Mexico to get access to the following strategic products:
Petroleum products
Crude oil (onshore, offshore, oil tar sands and oil shale)
Natural gas (onshore and offshore)
Coal
Mines in USA, Canada and Mexico
Minerals
Almost all the major industrial metals, plus rare earths and actinides (uranium and thorium)
Agricultural products
Almost all the major agricultural crops, including tropical agricultural products grown in southern Mexico
Renewable energy
Wind power from the upper US Midwest and in Alberta province in Canada
Solar power from the US Southwest and most of northern Mexico
Tidal power from off the coasts of Canada, USA and Mexico
In short, under the right political environment, North America could end up being the big winner in the long run.
Japan's been an economic powerhouse for decades - one of the world's largest economies - and they don't have ONE natural resource. Not iron, gold, oil, natural gas - nothing. Japan sits on a barren rock. It's NOT resources that count - it's the ideas behind a culture. If our ideas turn more 'left' we'll fail - - if 'right' we'll make it.
Don't fall for that old Marxist claptrap about 'resources'... it's a fool's game.
