This is a great point. Maybe it would be more in line with the facts to say that elite overproduction was "a contributing factor to the famines of 1300-1350 and the wars of 1350-1400". That doesn't seem to line up well with Turchin's secular cycle theory, though: 1300 is supposed to be the peak of the "integrative phase" and 1400 is supposed to be the trough of the "disintegrative phase". In fact, many of the "disintegrative phase" events happen well before 1350 (the Great Famine of 1315-1317, the Shepherds' Crusade of 1320, the Flemish peasant revolts of 1323) and many of the events that happened after 1350 could be explained more simply as effects of the Black Death. To be fair to Turchin, I think his thesis is that overpopulation and elite overproduction happens first, which then leads to famine/scarcity decreasing the non-elite population, which finally leads to a later period of warfare that kills off the excess elites as they fight for shares of the smaller pie. But I think the claim that this process happens for all societies on a 200-year sine wave warrants some skepticism.
