If you look at the history of places like Iran, or more recently in Syria and Venezuela, the conditions you're describing are just as likely to lead to a mass exodus and a civil war of the remainders as anything like a successful revolution. The "Arab Spring" was also driven by issues with water and the subsequent impact on the local economic situations, and they KIND OF succeeded... for a while. Now it's all back the way it was, or worse. The idea that misery inevitably leads to revolution is driven by narrative selection, not reality. In reality countries like the DPRK for example simply ate the cost of a million+ starving to death and then went 'happily' onward. There's a reason that successful and lasting revolutions are exceptional, not the rule.
