I watched that Age of Greed film you put up the other day, in fact I watched it several times and even went so far as to look up several of the points he made to get a better understanding of what was being said. One of the first points made was that the crises we face today were down to individuals actions.
One man says it's a tree. No, says the next, it is a snake. You are both wrong, says the third, it is a brush. Would it be possible to keep all the observations long enough in memory to realize that it's an elephant. Having to move the spotlight around all the time but having everyone forget what they've already seen makes things difficult and it means having to go over all the parts again and again (though hopelessly I fear).
Individuals act because they are the only actors. They must act individually but they can act according to common plans if they want to be more effective (or they can act just outside of a common plan to attempt to gain further advantage at the expense of their fellow conpirators at the same time as nbenefitrting from the conspiracy).
The term conspiracy may be too specific (and highly ridiculed by the media) to be an effective description but is a good general term nonetheless for what it describes. It can encompass the deliberate plans of groups (in my company we conspire, among other things, to take market share from Cisco - that's not a secret - but what we are planning IS a secret and I cannot tell you what I know - and that is just NORMAL BUSINESS. Cisco conspires, among other things, to stop us).
The concept of this all being handled or choreographed from above by some supah seakrit (or not) organisation has yet to be proven and requires some spurious leaps of logic in order to get it to fit.
Of course, if they were "supah seakrit" but for the most part they are merely under reported. Yes, things DO get choreographed from the top. Almost all organizations of significant reach and impact are hierarchical. That is SO normal it is easy to overlook. Soldiers act, generals command. And everyone down the chain of command will keep their mouth shut about what's going on, and mostly won't have access to the full plan anyway, because they are "all in it together" - they believe in what they are doing, don't leak and do as they are told for the greater good. Only the elites know the full plan.
Of course, they run up against someone else's soldiers run by some other elite with their own plan and things don't go as "desired".
