What is the role of business in the economy of a country?

In any
capitalist economy, businesses play a
huge role.  Businesses are the major provider of jobs and
the major drivers
of economic growth in a typical capitalist economy.

In a

capitlist economy, most workers are employed by private businesses.  This means that it
is up to
businesses to create the jobs that allow a country to grow
economically.  If private businesses
do not expand and/or if new private
businesses are not formed, the country's economy cannot
grow.

In this way, businesses are the most important part of a typical

capitalist economy.
