rising

Explanation:

Within political and social science the notion that unfulfilled, rising aspirations generate unstable political circumstances has a long tradition. James C. Davies used those cases in 1969 and a systematic model of the relationships between increasing expectations, satisfaction level, and radical upheavals was proposed which was named J-curve hypothesis. He concluded that the deciding relative deficiency was not between groups, but between one group's anticipated satisfaction and actual satisfaction. And therefore rebellion was caused by an unbearable disparity between what people want and what they get.
