No, my academic background is political science, not history, but they overlap. 'The exception that proves the rule' is generally trite, but I think if holds true in the case. Part of why revolutions are studied is that they're rare. Most modern human history is a story of unequal distribution of wealth and the exploitation and coercion required to uphold that, and the moments in history where that bubbles into revolution are rare. It's easy to say the French revolted in 1789, but that ignores centuries of the ancien régime remaining in power.

Conditions won't just deteriorate until an eventual revolution. A revolution itself generally can't be planned, but successful ones take a lot of groundwork.
