As our national debt races toward the $10 trillion mark (for Amercans), consider this: A million dollars is a stack of tightly bundled 1000 dollar bills 4 inches high. A billion dollars is bundles of thousands 300 feet high. A trillion is a stack of thousand dollar bundles 63 MILES high! Check my math if you want but I checked it myself several times and it's legit. Ouch! how do we pay off that kind of debt?
