The theory is that some system is inherently bad or broken but people in general don't quite realize it, so if it gets worse it will be more obviously bad and then they'll then actually deal with it. Although sometimes this kind of behavior does happen (for example, someone choosing to go to a doctor only after an illness takes a serious turn for the worse), it seems like a risky theory of social change.
Maybe the powers or institutions you oppose are more entrenched or more adaptable than you expect, or maybe the public is less sympathetic to your analysis of the situation than you expect, or less motivated or more defeatist.
