Marc Faber comments on USA economy : The federal government is sending each of us a $600 rebate. If we spend that money at Wal-Mart, the money goes to China. If we spend it on gasoline it goes to the Arabs. If we buy a computer/Software it will go to India. If we purchase fruit and vegetables it will go to Mexico, Honduras and Guatemala. If we purchase a good car it will go to Germany. If we purchase useless crap it will go to Taiwan and none of it will help the American economy. The only way to keep that money here at home is to spend it on prostitutes and beer, since these are the only products still produced in US. I’ve been doing my part .
He made this conclusion in his monthly bulletin in June 2008, but for those who wants to help economy this receipt is very timely for today also
