No longer welcome

People interested in social change do not have to figure out how to overthrow the power structure. That will happen by itself in due time. The key to bringing about social change is in figuring out how to keep the power structure, or whatever degenerate version of the power structure is ultimately left standing, from reclaiming the power once it has lost it. 

To accomplish that, it will be crucial as rapidly as possible to embed the power into the people. That embedding will have to be rehearsed ahead of time so that by the time the collapse happens and the power elites are in disarray, the ordinary citizens will be in position with mutual aid to take over the instruments of the public space and to fill the space with the revelries of celebration and permission and transition. 

At that moment, in the aftermath of collapse, as the dust is settling, as it were, one vector will have to address the civil society to make sure community spirit has not been impaired and that the sense of common membership will go on and survive the disaster. Another vector will have to address the power elite to disabuse them of the notion that their hold on power might persist once things have come back to normal. 

In other words, the way the general public will have responded to the collapse will be significant. A narrative of self-possession among the grass-roots needs to take hold as quickly as possible so that:

1. the people come to understand what it means that they will have been able to respond as effectively as they did, with love and mutual aid; and 
2. the incumbent power elites will be brought to understand that their leadership is no longer welcome, that a new day has dawned, and that their authority has become illegitimate.
