According to Alexander Hamilton, what was the proper role of the new government?

The most important role for the new central government
was, in  Alexander Hamilton's view, to create an environment in which business could
prosper.  Hamilton envisioned a country in which merchants, traders, and industrialists
would lead the economy.  It was the role of the national government to make an
environment in which that sort of economic activity could
thrive.

It was for this reason that Hamilton set in motion
his "American System."  Hamilton wanted a central bank, tariffs, and internal
improvements.  All of these things were meant to make it easier for industry and such to
get established and grow in the new country.  For Hamilton, the government was not
supposed to be a small thing that got out of the way of small farmers.  It was, instead,
supposed to be an active part of creating a mixed, modern economy in the
US.
