An update:

I’m  giving gave an open lecture/presentation at the college today Oct 20 on the future viability of Social Security and the crisis rhetoric surrounding it. It’s available to view or download here: Powerpoint file Download (no sound).

I had plans to make a video out of it, but time has gotten the best of me.  So, I’ve posted the audio-only from the presentation.  Listen to it while you watch the slides.  Sorry, it’s not edited so it starts slow but it’s all there.  Download the MP3 audio file:
