If the Nation can issue a dollar bond it can issue a dollar bill. The element that makes the bond good makes the bill good also. The difference between the bond and the bill is that the bond lets the money broker collect twice the amount of the bond and an additional 20%. Whereas the currency, the honest sort provided by the Constitution pays nobody but those who contribute in some useful way. It is absurd to say our Country can issue bonds and cannot issue currency. Both are promises to pay, but one fattens the usurer and the other helps the People.
