The Grand Narrative of the 21st century is the legitimization of the authoritarian state. The authoritarian state comes in many ideological flavors, but retains the commonalities of central control. It may label the system it controls communist, socialist or capitalist, but these distinctions are semantic: the authoritarian state controls the system, by one means or another.
Regardless of which version of the 9/11 story you believe or disbelieve, the reality is the same: the U.S. is engaged in an Orwellian global war without end, a war that doesn't just justify monitoring every communication on the planet but actively requires monitoring every communication on the the planet.
The Federal Reserve has extended its control of the U.S. economy, transforming it into a wealth-skimming machine for the top 1/10th of 1% with access to the Fed's credit creation. The Fed claims independence from the U.S. government, but this is also merely semantics: the Fed and U.S. Treasury are simply two facets of the authoritarian state.
We see the same narrative playing out around the world. In socialist France, the central state is extending its control over what little of the economy is still quasi-private; in nominally communist China, any weakening of the economy that can't be papered over with bogus statistics is soon followed by nationalist propaganda hyping one red-button issue or another (Senkaku Islands, etc.) to distract the populace from the increasingly fragile "recovery" in China's asset-bubble-dependent economy.
As the status quo crumbles, the state responds in the only way it knows: expand control and become increasingly authoritarian. This is of course a key dynamic in why things are falling apart: increasing central control only further distorts the mechanisms in the economy that seek equilibrium by self-correcting means.
Why is the authoritarian state illegitimate? Among the many reasons, we can start with three: the authoritarian state is the enemy, always and in all places, of individual liberty and free expression/the free press, and the authoritarian state is intrinsically a failed state, for the mechanisms of centralization and authoritarian control are ontologically destabilizing, regardless of the ideological flavor of the system the state controls.
