Final answer:
The culture of the 1970s and 1980s emphasized identity politics, reflected economic and political shifts, and was marked by the rise of hip-hop music and 'yuppie' culture.
Step-by-step explanation:
The cultural landscape of the 1970s and 1980s in America was deeply influenced by a variety of factors, including political events, economic changes, and social movements. During the 1970s, the rise of identity politics became pronounced, as individuals began to focus on issues significant to various cultural subgroups, such as ethnicity, sexual orientation, gender, and religion. This was partly a response to the disillusionment with the possibility of a unified society and in part driven by the civil rights movements of the previous decades which continued to evolve.
The 1980s saw the influence of economic and political shifts in American culture, exemplified by an increased emphasis on material affluence and the emergence of the 'yuppie' culture. This period also witnessed a significant cultural movement with the spread of hip-hop music, which began in inner cities but rapidly gained nationwide popularity. Meanwhile, American society was also grappling with economic challenges such as the decline in manufacturing jobs and a shift in population towards the Sunbelt regions.
