It seems similar to the construction in the phrase, "When two people love each other, there can be no happy end to it." I'm also reminded of Jefferson's quote, "The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants. It is it’s natural manure."

I think I agree with you/them - eventually, the stochastic processes of politics will yield despotism, that natural attractor from which we may break away only with difficulty.
