Brother Dave sent us this speech by Bill Moyers. In his speech, Mr. Moyers more cogently covers much of the territory I have been pondering. He also has a better sense of history than I. I strongly recommend you take the 15-20 min to read the speech. And see if you can spot the same slight historical inaccuracy I did (I suspect it was a typo, since Bill M. would have none the date intimately).
