Big changes can happen to wealth distribution. In the twentieth century those were WWII and the Reagan presidency. Both profoundly changed wealth distribution. Below we have an economy undergoing such a transition in periods A, B. Given are decile distributions (example, for the poorest 20% of the population system A pays 4% of the country's wealth to this segment whereas B pays 2%).

CAUTION: The deciles below are cumulative, hence any change is carried forward and felt long after. For example decile 30% have a 3 (9-6) difference. However the difference brought about by 20-30% really is only 1 (9-4 versus 6-2).

When graphing the above data, they resemble old uneven steps. If system C has the top 10% enslaving everyone else then the distribution no longer resembles steps, but looks like?
