Homeostasis of Human Society
So I was thinking about Russia, right, and between Imperial Russia, the Soviet Union, and modern Capitalist 'Democracy' Russia, you have three wildly different governmental structures and ideologies, but somehow they all seem more like each other than they do like anything else, implying some kind of homeostatic mechanism that keeps a society more or less in equilibrium even as you poke at it, for better or worse.
If you read Lenin's "State and the Revolution" (1917) it's quite clear that the dictatorship has been the plan from the very beginning, and it was quite extensively supported by quotes from Marx and Engels.
