Federal assumption of the states’ war debts also yielded an advantage in terms of economic development: once states no longer had any debt, they had no need to raise any revenues through direct taxation, which might have impeded the growth of America’s internal market. Indeed, after the federal government assumed the states’ debt (already a small part of the total), state revenues fell by 80-90%.
联邦将各州战争债揽下还产生了经济发展的优势：各州卸下了战无负担，因此不必通过可能阻碍美国内部市场发展的直接税开源。事实上，在联邦政府揽下各州债务（只是总债务的小头）后，各州岁入下降了80—90%。各州也因此在一段时间内不必担心财政状况。
