Alexander Hamilton was appointed as the first ever secretary of Treasury by President Washington. He changed and largely developed the economy by proposing a National Bank among other things. He encouraged nationalism and production within America. Debts were to be paid off whether they were domestically or internationally from the war and war bonds.
