Many governments around the world seem constantly to be in a state of flux. Even in stable and democratically governed societies, leaders on the local and national level may change every few years with new elections. Yet under the surface, there often seems to be a "culture" of government that can resist change, even positive and necessary change.
It's possible for government to change for the better.
Bureaucracies sometimes become so entrenched, not only with long-term personnel but with narrow ways of thinking and acting, that the changeover of elective officials may have little direct impact on how government responds to the people's will.
