According to a historian theory, world events unfold in predictable cycles of roughly 80 years, that you can devide into 4 chapters (or turnings), (1) Spring (Growth), (2) Summer (Maturation), (3) Automn (early old age and reconstruction), and (4) Winter (late old age and destruction). There are strong parallels with the 1930s today.
