And there is a very simple reason why complaining has no real effect:
Because the complainers keep right on obeying.
As long as you obey, the things you complain about will keep on happening.
This idea that "nothing changes as long as you obey" has a modern proof – that of American blacks in the southern United States. Specifically, between the civil war and Martin Luther King Jr.
King is badly misunderstood. His legacy has become a tool for garnering of political power. He has been turned into a semi-mystical symbol and used by power grabbers of many types.
The real Martin King, however, was a minister who exposed the truth that obedience keeps us in chains. His crucial synthesis was to combine disobedience with goodness. His crucial work (and this is greatly under-appreciated) was to hold disobedience and goodness together.
