It doesn't matter anyway, it's all fiat money not backed by Gold and therefore worthless, created out of debt by the bankers and the Fed. A nation whose economy depends on fiat money is doomed. It has always been thus. The Founding Fathers knew the dangers of a central bank. But the House of Rothschild and the House of Morgan were patient. They waited. They bided their time and in the end, the creature was born on Jekyll Island. Now it's only a matter of time. It's either going to be the Jihadis or the Puppet Masters as Quix like to refer to them.

One of my prior jobs was as a Center Administrator for a debt management company. Trust me, they are making money from the people who have debt as well as the credit card companies. You are not alone, many have numerous credit cards and use them all, some to pay off debt to other credit card companies. It is a never-ending cycle. Our education system should teach our youngsters about debt and its consequences - something that would relate to the real world and help them to function with realistic budgets.
