Communism has a tendency to require greater levels of force in order to maintain state control.
And the the numbers financially are just getting too lopsided to maintain the uneven consumption for much longer. China will start to get a much larger share, and the bankers will have to go along with it, because of basic realities of math.
So the global military and economic control will shift to China, but before/during/after the primary economic model in places like the US will have to shift.
This means some people will have violent disagreements with the new control structure. So they are trying to lay the groundwork for a carefully monitored and controlled population now. Part of that is conditioning to not expect privacy, which is one main function of the TSA.
This is not a new situation or process really.
Not directly, but they both are connected to the overarching theme in American politics of "OMG TURRURRUSTS" (and the overarching subtheme of "our various means of removing the privacy of Americans are not actually doing anything they were marketed to do"; with this article, it seems that neither the TSA's security checks nor the NSA's surveillance are actually doing anything to stop terrorists).
