In fact, authoritarianism in one form or another, could become quite probable once things begin to really crumble. And they will, sooner or later. Of that you can be quite certain.
The inherent contradictions and absurdities of electrified Capitalism will accumulate in not only more and more fractured social cohesion, the physical limitations of what a cost based economy can respond to, as the planet itself begins to rebel as well, will make it almost mandatory for the ruling elites to enforce compliance by the rest of us by the harshest applications of rule by fear. And make no mistake. They will couch this in the grandest cache of patriotism and national honor possible.
Just remember. If Fascist thinking can take hold in Russia, who suffered at least as much as anyone else as a result of their rule, it can happen anywhere.
