Not sure how the Kulak thing applies here; the kulaks were more than welcome to continue existing as a class right up until they refused to play their role as had been defined by the state by not only resisting collectivization, but by actively sabotaging that effort by deliberately destroying their harvests in the midst of a national emergency. Had the famine not occurred or had they cooperated during said famine, the kulaks would still have existed as a class. Thus, I feel, is what China is doing right now; their own kulaks are perfectly allowed to run as-is, but if a national emergency takes place that needs their productive forces, those means of production are getting the fuck seized, and god help you if you resist.
