African - Americans began to challenge and criticize the nation's way of life in the 1960s not able to take the pressure and discrimination anymore.

The idea of "First hired, last hired" came around the period 'Great Depression' when the economic condition in the country was collapsing and the pressure was more for the African - Americans than the rest.
The wages of the African - Americans were simply very less and during the Great Depression the situation got more worse. Resulting in great debt. Therefore, the African - Americans began to challenge and criticize that nation's way of life in the 1960s not able to take the pressure and discrimination anymore, which began with the Civil Rights Movement to Civilian Conversation corps including higher education, health and proper wealth.
