A culture or civilization that is not expanding is contracting and there is external and internal forces ready to overporwer them,
The dominating culture will begin losing power as it is subjected to recurrent falseation, attacks and "trial and error" from iterations of competing cultures, as these begin developing subsistance mechanisms and economic support network to "counter" it, the dominating culture will remain in erosion until its fall as the competing culture garners sufficient labour, momentum and power to lead a revolution, normally what accumulates sufficient labour to change the zeitgeist is a change on the productive structure
For example, the bourgeois revolutions entailed the accumulation of induatrial labour and agricultural produce in enriched peasants and bourgeoise, this led to an accumulation of capital (exchangable labour) that would eventually permit a replacement of the previous economic-productive structure (feudalism, which divided the Managerial classes, property ownership/war means and subsistance farming to lock this developement)
