The institution exists only because most of the people can still benefit from it, in another word, it still represents the majority people's will, whether it's democracy or authoritarianism. However, once it's falling, which is always going to happen, one way or another; once people is not benefiting from it, then they will ditch it. The difference is this process will happen in a civilized manner, if it's a democratic system. Otherwise, there will be a war, a revolution. Someone will die, a lot of people will suffer.
