I used to be a bit sanguine about the prospects general category of benefits for retired people. I figured that old people vote, there are more and more of them, and no one's really going to be able to screw them out of their benefits. Hell, even George Bush expanded Medicare, if in a somewhat flawed way.
But I didn't anticipate the "vote to cut benefits for people not yet retired some decades in the future" gambit. That one just might work.
