And strikes happen for the same reasons that revolutions happen. If a system is under stress, eruptions are pre-programmed. The size and trigger for specific events are unpredictable, but the causes and overall dynamics are not. One may try to delay / reduce the impact in controlled releases through various safety valves, but sooner or later, if the internal contradictions are not resolved and the systems means to alleviate the stress are exhausted, revolutions will happen (see this for more / the general). ^335c11
