Let's take the 'after' part first, as we have said before that we do not have 20-20 hindsight, in many cases, though our 'ex post facto' state may be wiser (not necessarily, to which any thoughtful human will attest). This New Yorker article ought to help understand some of the issues. The Atlantic had a similar one (Lies, Damned Lies, and Medical Science), recently.
Now, on the before side, it's not easy either. The qualification, frame, ramification triad and undecidability apply, for the most part.
Now, we have another thing to ponder, especially when putting our seats on an airplane. But, as with all things technical, worrying about some of these things is just too difficult. Full speed ahead (paraphrase, as the context also demanded to ignore the torpedoes).
But, is this not true: any successful, democratic society requires a knowledgeable populace? Of course, there is the issue that we cannot let paralysis come from analysis.
So, in this case, we'll look at the issues from several sides even though one player says that it's of no concern. Expect the discussion here to continue, in a supportive role, while the video is analyzed.
12/20/2010 -- Not only do we need to ask who tells the truth, we need consider what 'truth' might be. A recent New Yorker article is of essence: The truth wears off. The few sentences of the article says this: "Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean that it's true. When the experiments are done, we still have to choose what to believe". I might add, whom to believe. A similar article appeared earlier in The Atlantic.
Then, that same issue of the New Yorker has an article about the hypocritical mantras of 'free markets' that we're subjected to (Enter the dragon).
12/18/2010 -- On the finance side, Martin Weiss reminds us that Big Ben has grown the money supply by 1.2T the past couple of years. Then, he lowered the cost (interest) while giving bunches of money to the banks. These guys then loaned the money to us at a high rate of interest. And, pulled in the bucks. Of course, Ben had taken 1T of toxic assets off of their hand and put it on our backs. Finally, those jerks are getting paid big bonuses this year. We should have nationalized, yes, indeed.
