I don't see a "claw-back" system working, even if it were put on the table. The elderly tend to vote en bloc, and they have historically resisted any cuts in pension benefits, as in Social Security. It's doubtful you can count on this happening. Social Security cuts are known as the "third rail" of US politics for a reason.
Unfortunately, the "small government" advocates are going to defund the health care initiative we've got - the one that hasn't even started yet, because they think it's "socialism". You can forget universal health care.
After examining the posts from conservatives on this board, do you honestly think they are willing to accept any tax increase at all? I'm also uncertain who would be deemed "wealthy", but usually anyone who is denies it strenuously, in my experience.
Yes, we have the technology to feed, clothe, house, educate and provide medical care to all our citizens. If we didn't do these things during propserous times, what makes you think we'll do them in lean times?
What do you say?
