The Constitution, although not an ``economic document,'' was born out of economic necessity. Congress and the states were bogged down in challenges regarding trade and tariffs, debts and currency, under the weak Articles of Confederation, which gave too little power to the central government.Many economic powers have been granted Washington under the Constitution: the power, for example, to lay and collect taxes; to coin money and set its value; to regulate interstate commerce; to promote the sciences and arts.
