In their book, "Generations," William Strauss and Neil Howe (S&H) opine that there are occasional "Eras of Good Feelings," such as the original one (1815-1830), and similar periods following a "secondary" war (e.g. the 1950s after the Korean War). Even though such eras are actually riddled with lots of political issues, S&H believe that "compromises" such as the Missouri Compromise are more likely to take place at such times than other times in American history. Why did they believe this? Do other historical authorities share this view?
William Strauss and Neil Howe's (S&H) hyothesize in "Generations," that "compromise" type generations are born just before, and grow up during a major American War (e.g. the Revolution or World War II). They enjoy a prosperous childhood as a result of that war, and come to national leadership following a "secondary" war (e.g. the War of 1812 or the Korean War), which they "draw."
Their childhood experience is one of "enough for everyone." Their young adult experience is that "It's best to split the difference." They spend their leadership tenure doing that, making compromises, and "sharing the wealth."
The original "Compromise" generation included great philosophers such as Henry Clay, John C. Calhoun, and Daniel Webster. Hence, they authored the "Great Compromise" or the Missouri Compromise to try to keep both the North and South happy, and delayed the Civil War for a generation (during their leadership tenure). After the Compromisers "retired" in the 1850s, the dam broke and the Civil War started.
A more recent "compromise" generation (i.e. the Silent generation of Ted Kennedy and Warren Buffett) realized that "everyone" except women and minorities had "gotten theirs" after the Second World War, and brokered a series of compromises that led to the civil rights movement. S&H believe that the "Homelander" generation (born after "9/11") may become the newest "compromise generation.
S&H have attracted a group of followers such as Morley Winograd of Marshall University (who was born in 1942 and is a member of the Silent generation). Yours truly also considers himself a follower of S&H.
