We have just had an election which may have affected the outlook and hope that each of us hold for the future.   However, regardless of which side of political fence you fall on, please consider watching this short 52 minute documentary, then give some thought to an even bigger picture looming in our midst.   I urge you to watch the entire doc.  It's thought provoking, and the latter half can be an eye opener, depending on how you view our lives, our politics, and our country's future.

ps. It's also available via Netflix streaming

The one I thot was a little more in-depth was the doc called "The Corporation".   Ethos is, like you said, a primer, but still enlightening, at least for the great unwashed.
