Of course, different racial minorities experienced the 1950s in ways that were at least somewhat different from one another. We can generally say, however, that minorities experienced the 1950s as a more negative time than whites did.
The most prominent minority group in the US during the 1950s was African Americans. During this decade, they were still experiencing much discrimination. This was the decade of the Montgomery Bus Boycott and the harshly negative reaction among whites to the integration of the high school in Little Rock. Things went beyond mere discrimination as well. This was also the decade in which Emmett Till was killed for talking to a white woman the wrong way.
Hispanics and Native Americans also experienced the 1950s negatively in some ways. This was the decade in which the federal government was willing to try to deport large numbers of illegal immigrants and felt that it was appropriate to name the program “Operation Wetback.” Native Americans suffered in this decade as the government tried to pursue a policy called “termination” that was meant to disband Indian tribes and force Indians to assimilate into mainstream society.
Thus, while not all minorities experienced the ‘50s in the same ways, minorities generally had a poorer experience in this decade than whites did.
