cited here is that they were testifying truth to power in every sense.

Most of their testimony is essentially correct; one could quibble about war for oil and reindustrialization plus a few others but those cited are basically correct in their assertions. We need to fix a lot of things.

Every thing we need to fix that we can indeed actually fix can be laid directly at the feet of Congress. This or that President may have facilitated what Congress wanted but those guys only serve for four or eight years -- as all the testimony above shows, we've been headed downhill since the '60s. Only the Congress has been around that long. So congress can do the fixing. Somehow, I doubt Congress will fix itself...

Thus, we need to fix Congress.
