The writer points out that the change in America from an agricultural to an industrial economy ____ .

Today, the United States is in the grip of a second
Industrial revolution. While the first, stretching from the
1870s to the 1970s, shifted the main sector of the
American economy from agriculture to industry, the new
revolution is shifting the economy away from traditional
"smokestack" manufacturing industries to those based
upon information, services and new technologies. It took
the country decades to accommodate the cultural and
social changes resulting from the first industrial
revolution and it would be rashly optimistic to assume
that Americans will not face serious stresses in coming to
terms with the changes that are transforming the
workplace today.
