poor pay and discrimination.

Explanation:

After the Second World War, Hispanic Americans still faced widespread discrimination in hiring, housing, and education. Poverty was widespread. In 1960, for example, the median income of a Mexican American family was only 62 percent of the median income of a family in the general population. Hispanic American activists during the fifties and sixties mirrored the efforts of black civil rights leaders. They, too, denounced segregation, promoted efforts to improve the quality of public education, and struggled to increase Hispanic American political influence and economic opportunities.
