Describe the impact/legislation passed as a result of Upton Sinclair's book, The Jungle?

One of the
most significant impacts of Sinclair's  was to raise questions about the
potential dangers of capitalism.

Indeed, the
legislative impact of Sinclair's work can be seen in the passage of the Pure Food and Drug Act
in 1906.  However, Sinclair has a wider purpose in writing the book.  He wanted to shine a light
on "the inferno of exploitation [of the typical American factory worker at the turn of the
20th Century]."  His work depicts a world where profit is deemed more important than human
beings.  While Sinclair focused a great chunk of the work on food preparation, one of its
greatest impacts can be seen in its depiction of the economic and social struggle of American
workers.  Sinclair's point of view is a Socialist one, which sought to bring voice to the
workers.  

The Jungle helped to shed a much needed light
on the inhumane conditions that workers and immigrants endured.  Upon reading Sinclair's work,
then- President Roosevelt believed that "radical action must be taken to do away with the
efforts of arrogant and selfish greed on the part of the capitalist."  In this way, it is
clear that one of the most enduring social impacts of The Jungle was to
raise questions about the presence of unchecked capitalism in American
society.
