Why are we so concerned about what generation you come from?

Normative history-graded influences are common to people of a particular generation within a specific society. Due to historical circumstances, a wide-sweeping occurrence, such as the Vietnam War, greatly affects each generation a particular society in a great, but unique way. For example, the younger generation’s members were drafted and exposed to the horrors of war while the older generation debated to the political and economic implications upon the country. These events became normative when the event was unavoidable, discounting extreme circumstances, and held a lasting and gradable effect on a significant amount of at least one generation with the society.
