The author of this article actually knows what he's talking about. He covered the material and broader issues well.
It's amazing, lifetime savers who wouldn't touch anything other than CDs or T-bills a few years ago are now running to the junk bond market. They'd be better servered in the stock market with lower risk.
That aside, I think it would've been nice for the author to add in a comment or two about how (since SS only 'invests' in governmnet bonds) how these low inteest rates more or less sap the SS fund in order to support business ventures. In a way I like the idea. It's about time the Boomers paid their way, I just don't think they were expecting to be doing it with their SS money.
