most of the makers of the Constitution had some direct economic interest in establishing a strong federal government: the manufacturers needed protective tariffs; the moneylenders wanted to stop the use of paper money to pay off debts; the land speculators wanted protection as they invaded Indian lands; slaveowners needed federal security against slave revolts and runaways; bondholders wanted a government able to raise money by nationwide taxation, to pay off those bonds.
