The wheels in India have come firmly off the carriage and unsurprisingly last weeks imposition of draconian capital controls have sparked, rather than stopped a creeping sense of economic crisis and currency collapse. Russia will shortly be in rapid decline as coming access to cheap "fracked" energy brings its recent economic clout to a swift demise. Economic growth has stalled in Brazil and this has been reflected in nationwide protests against its rent-seeking state and high cost of living.
America, on the other hand has no such problem. It is completely food self sufficient and always will be once it controls the worlds largest bread basket in the Mid-West and the Mississippi delta.
Ironically from here in Western Europe it is clear that these bouts of "decline paranoia" actually usher in a period of ferocious capitalist house-keeping - in a way not possible in Europe's socialist market economies.
