Many upper-class Americans complained that state constitutions were too democratic and, as a result, legislators were more concerned with maintaining popular approval than doing what was best for the nation. The most pressing example was the way state legislatures responded to calls for economic relief in the 1780s. Many people were unable to pay taxes and debts due to a post-war economic depression that was exacerbated by a scarcity of gold and silver coins. States responded by issuing paper currency, which often depreciated in value, and by making it easier to defer tax and debt payments. These policies favored debtors at the expense of creditors, and it was proposed that Congress be given power to prevent such populist laws.
