Assess the validity of this statement: The progressive era was a failure

I am not
sure I entirely agree with the statement.  I would concede that the Progressive Era sought to do
more with its hopes and aspirations than prior movements, and because of this high level of aim,
it might have given more reason to raise doubt.  Yet, I think that it accomplished a great
deal.  In an America that was driven by economic and industrial success, the Progressive Era
sought to bring more voices into the American discourse.  These voices might have been silenced
because they did not represent the wealthy or most powerful.  Yet, it is because of the
Progressive Era that the narratives of the poor, the working class, women, and individuals of
color began to be heard and integrated into the dialogue of "what it means to be
American."
