When the power of taxation is unlimited, as in the case of the national government and the sovereign States, there can be no question as to the ability of the political unit to meet its obligation, and the question becomes entirely one of good faith. It is probable that the obligations of the United States Government, by reason of the fact that the per-capita debt of the country is so small, the wealth of the country so great, and the good faith of the American people so clearly established, represent the highest type of security to be found in the world. It is quite possible, therefore, that the 2-per-cent United States Consols would sell in any case at a relatively higher price than the obligations of any other country, but it can not be denied that the chief reason which causes them to sell at the remarkably high price which they have attained is the fact that they are required by national banks as security for circulation. This fact is doubtless the controlling element in their market position, and at once accounts for their special strength and removes them from the field of private investment. Only less secure than United States bonds are the obligations of the sovereign States of the Union. State bonds usually sell upon a basis which may be taken as the equivalent of pure interest, with no element of risk or speculation involved. The obligations of different States sell at different prices, in accordance with market conditions and the relations of supply and demand, but there can be no question of the equal ability of all States to pay their obligations. Repudiation of State debts has occurred in our history, but only in cases where an overwhelming majority of the citizens were opposed to the creation of the debt at the time of its issue, but lacked the means to control the situation. Such instances are chiefly to be found in the case of the so-called carpet-bag governments of the Southern States after the Civil War.
