text_A: Gini was a proponent of organicism and saw nations as organic in nature. Gini shared the view held by Oswald Spengler that populations go through a cycle of birth, growth, and decay. Gini claimed that nations at a primitive level have a high birth rate, but, as they evolve, the upper classes birth rate drops while the lower class birth rate, while higher, will inevitably deplete as their stronger members emigrate, die in war, or enter into the upper classes. If a nation continues on this path without much resistance, Gini claimed the nation would enter a final decadent stage where the nation would degenerate as noted by decreasing birth rate, decreasing cultural output, and the lack of imperial conquest. At this point, the decadent nation with its aging population can be overrun by a more youthful and vigorous nation. Gini's organicist theories of nations and natality are believed to have influenced policies of Italian Fascism.
