I strongly doubt this guy has enough data, background, experience, training, etc. to be able to put together a good guess as to why the cycles he thinks he's measuring are there. And when you don't know why, you get problems like this:
86, 77, 68, 59 - what comes next, and why?
Kondratieff was unfortunately executed by Stalin for his idea that economic cycles come in long waves, either 50 years or 40-60 years. This was not consistent with Stalin's plans for onward and ever upward. But the idea of "long waves" has stuck around, being applied to the rise and fall of empires, world economic cycles, economic performance at the national level, the rate of innovations, and crime rates.
Explanations for why things ought to come in long waves have not been very impressive, IMHO. It is not always considered necessary to offer an explanation; maybe one will come forth some day. The idea is applied as a sort of macro magic that is beyond human control; it just happens, sort of like the planets rotate around the sun quite regularly. It is not nearly as sophisticated and empirically grounded as theories about overshoot of a species' food supply.
Demographers talk a lot about "the demographic transition," which is a set of observations, not a theory and certainly not a "law." The observation is that the death rate begins to fall before the birth rate falls, with a period of indeterminate length being a period of natural increase in the population. We saw this in Europe, in the U.S., now in Latin America, and in some Asian countries. It is not known whether and when countries that presently have high fertility might drop those rates, but until they do, their populations are growing.
This is not a long wave theory; it is simply a collection of facts. There is no Kondratieff theory involved. History is better built on collections of facts than upon dubiously relevant theory.
I think it is simply wrong to claim that bringing long wave theory to history will make history scientific. If anything, it is likely to make history obsessed with magic cycles.
