What is the author's style in The Fourth Turning: An American Prophecy by William Strauss?

The perspective of The Fourth Turning is one that attempts to stand above ideologies and cultural trends. The authors attempt to stand astride history and view broad generational trends in social attitudes, the rise and fall of individualism and communitarianism, the ebb and flow of traditionalism vs. progressivism in moral attitudes, civic pride vs. alienated and so on.
