Well, fwiw, all our savings went into a fix investment account sincel 1997 when I got tired of worrying about big market moves. I know I'm not a risk taker like many here but in retrospect we saved at a high rate of our income (20-30%) and with our fixed investments we've managed (lucked out) to avoid the Dot.Com, 911, and current crisis.
No doubt, with the drive to very low fixed rates it seems to me the intent is to drive people like us to put our $$$ in equity in order to rev up the economy rather than hoard it in fixed accounts.
Since we're both retired (me & DW) we'll stay in 100% fixed- (3,4, or 5% return will work nicely) well, only if our investmet firm does not go belly up
