Change in socio-economic classes

We are discussing Reza Khan's Iran and a lot of that in the beginning revolves around reforms that he made. There was an aspect that came up about the poor supporting his changes because they were desperate whereas the more affluent were not particularly keen on bringing about change because they were content with the way their lives were. So a question was posed about change in socio-economic classes and about how the lower in status that they are, the more they believe that they should work to ameliorate the society. The elites disengage themselves whenever they can because they are ultimately selfish and do not want things to change for themselves as to aid the poor and grant them more privileges. Looking at history, there is a pattern where this continuously happens where the rich do not support change, and the poor are willing to do anything for it. This is because the poor feel they do not have anything to lose and that any hope of change would be better than the lives they're leading. In addition to this point is that whenever things are looking up and more people are employed and there is no hyper inflation, people begin to stop supporting radicalism. Before world war 2, when the Weimar Republic induced a 200% raise in unemployment, everyone looked towards the NSDAP to bring about change, whatever it took. But as Stresemann, the foreign minister at the time introduced the Dawes Plan, reducing overall German reparations, the NSDAP temporarily became unpopular because people were content. This shows us a recurring prototype where people looks towards bringing about change only in times when they are desperate but when their personal situation is not declining, they immediately stop caring about altering circumstances for the rest of society.
