I meant "preserving the status quo" as meaning "society remains roughly in the same shape", ie no violent upheavals, revolutions or other drastic changes that would disrupt the ability of an average citizen to keep making a living. Think overthrowing congress in favor of a military dictatorship, or a couple of states seceding and trying to take the nuclear weapons stationed there with them. In that sense most of the western world hasn't seen that much "real" upheaval in the past century despite massive technological changes. We still have democracies that operate on mostly the same principles as a hundred years ago, sometimes with many of the same political parties as a hundred years ago as well.

Relatively slow improvements to living conditions are fine, as that does not cause massive disruption for the average citizen and does not threaten whichever groups are in power.
