What did the experiences of Hispanics, Asian Americans, & American Indians reveal about the United States in the 1950s?

In terms of overall experiences in a post World War II America, each of these groups understood what it meant to be silent in the American discourse.  Simply put, this means that the vision of American success did not necessarily include these specific groups.  They were relegated to the margins, as their particular predicaments were not necessarily included.  In the 1950's, few stopped to ponder how these specific groups would face difficulty in the America of the time period.  Native Americans were not thought of in terms of empowerment or even partaking in the vision of economic and social success.  There was little assistance offered to Hispanic Americans or Asians coming into America.  In all three situations, to partake in American success forced a direct conflict with maintaining their own sense of ethnic/ racial identity.  Assimilation became akin to sacrifice, and these particular groups' were not able to give voice to their own sense of experience and narrative in the American discourse, as a whole.  The vision of America did not necessarily include these particular groups' experiences, which might have led to much of the activism in the 1960's, as a form of giving voice to those who lacked it.
