I didn't know how JP Morgan Chase and Goldman Sachs made $6.8 billion in profit last quarter but then I read How Wall Street is making its billions.
the big investment banks are able to borrow money from the U.S. government at 0 percent interest. Then they can turn around and buy short-term bonds that pay 2 or 3 percent annual interest. Now they’re making 2 percent on whatever they borrowed....
Are they investing the money in American business? “No, they are mostly buying Treasuries.” So the money is just being shuffled from one Federal bank account to another, with each Wall Street bank skimming off $1 billion per month for itself? “Pretty much.”
