Revolutions happen when obstacles to pressure are removed, not when they are created.

Evidence

Revolutions thus occur when obstacles to strong pressures are unblocked; they are not, as typical contingency theorists believe, the very result of blockage. Hence the assertion in our explanation-sketches: for inherency theory, the pivotal problem is what prevents extreme conflict from taking place; in contingency theory, the issue is what causes it at all. — John T. Jost and Jim Sidanius, Political Psychology, 4306
