Class, as a fractal structure, may have causal dynamics which change dramatically at each bifurcation. That is, the effects of class position may produce one kind of result in one part of an outcome field and another result in a different part of the outcome field. The concept of a 'feedback loop' is a better term to use to refer to the causality of class structures. Class dynamics with positive feedback loops tend to explode, that is, inequality becomes so great that bifurcations occur after which boundaries are hard to discern. Monopolies are exemplars of positive feedback and entrainment.
Class inequalities tend to disappear with negative feedback.
Progressive taxation is a form of negative feedback. In terms of capitalism and class strata, it may be the case that some inequality, based upon technical divisions of labor promote economic health. For example, 11. Social control and human agency becomes ever more difficult as bifurcations explode to fill the space available to them. Planning and goal attainment are very difficult in deeply chaotic regimes.
