And a good op-ed by Krugman the other day:

[...] Social Security's attackers claim that they're
concerned about the program's financial future.
But their math doesn't add up, and their hostility
isn't really about dollars and cents. Instead,
it's about ideology and posturing. And underneath
it all is ignorance of or indifference to the
realities of life for many Americans.
