The leaders of any status quo cannot self-propose changes to the status quo under which the leaders cease to be the leaders.
Or, put it another way, proposed changes in a status quo by those most benefiting from the status quo will be socially invariant.
Corollary 1: Change comes when the leaders screw up and propose a change intended to keep them the leaders only to find it does something else.
Corollary 2: Change comes from the outside and the edges and the unexpected.
