1950s and 1960s were about growth and optimism where the 1970s became about recession, distrust of government, and a conservative wave of politics.

Nixon would also contribute to distrust of the government with the Watergate scandal. Lastly, the US will experience job-loss and recession in the 1970s with 'stagflation' and a end to post-war growth.
