What about the many times in history where that was effectively not the case ? I mean, say, take a Russian living in 1905 under the Tsar. Odds are very slim indeed they would have lived to the point when times/rules got better again. Or a Chinese living in the 1920s ? Rules relaxed again in both cases, but those people would have died long before the rules changed back.
