i've just watch a announcement speech from a ceo of Agora.inc Bill Bonner,that has stated this country(usa) is heading for a bad systemic shock,stating;americans are using more & more credit than the cash supply has to cover it .Theres about 4.5 trillion $$ in credit debt now,and only about 250 billion $$ in use in the usa ,its just exchanging from one hand to another.he also stated that if 1 company loses faith in getting its $$ back from all the credit ,it will slow down everything in its path,causing economic shut down. i'm sorry i cant get a link to prove this
