with whatever said so long on economy with the so called scientific approach and all we could see the american economy collapsing to the worst impacting others kitty also. these so called educated scientific economic analysts theories always fail.these people do not have any practical approach for analysing things.econmy is tied up with hunger and with the thirst of man to resolve hunnger.it is also attached with social sntiments.so no one can predict accurately.so whatever the economists say can be taken only as a guideline.these theories should only guide mankind not to commit any blunders in economy.but we witnessed is the sheer reverse based on the wrong economic theories,like subprime mortgage issue, the technical charts for forward contracts and various derivatives .these things are highly misleading and based on this if actions are taken with high dreams on fortunes,anybody will end up only in difficulties.
