1) Personally I think that you have it exactly backwards. If you look at Western Europe and all the social services provided there, they don't do it by going after billionaire's money because there simply aren't enough of them. They do it by having significantly higher taxes on most above average incomes.
In the US, when we focus the discussion on the ultra rich and move it away from the merely well to do, we take the discussion away from what has to happen if we want things like single payer health care or vastly cheaper college education.
2) Also, for the record this is a little questionable:
compared to the 1%, most of whom still have to actively plan for retirement and worry about financial security
To be in the 1% of wealth you've got to have over 10 million dollars. If you've got that much on hand and you're all that worried about retirement you either can't do math or your idea of a comfortable retirement is quite lavish.
