On the other hand, I reject his cries of paternalism for the simple reason that other people's poverty has a negative effect on my life, liberty, and pursuit of happiness. Poor people have incredibly high rates of criminal activity, drug use, etc. Granted, I don't see a lot of retirees selling crack or robbing banks, but the effect it could have on their families, who sometimes they support or sometimes support them, could create a serious ripple down through generations.
Which doesn't necessarily mean I'm for Social Security or forced savings of any kind, but the issue is not nearly so simple as paternalism.
