Vibrant countries seem to have "started again" more recently than more stagnant ones. E.g. Gernamy and Japan were "re-started" after conquest, China was restarted after a takeover by new people from the PLA and Communist Party, Georgia after a new police force. Startups and successful businesses thrive in countries with more lenient bankrupcy laws. This ensures the decay-death-rebirth rolls around quicker.
