I'm counting on $0 being paid to me by the government when I retire. If I end up getting 78% of what I was "supposed" to receive, then I will be pleasantly surprised. I sock as much money into my 401k as I can every year, and it's fun to watch it grow (yes, mine has actually grown in the past couple years, thanks to some very strategic moves on my part).
Even my 401k doesn't make me feel completely comfortable though, because it's based on the American dollar, which may not even exist anymore by the time I retire. I want to start buying valuable things that I can actually bury in my yard, like gold and platinum and "stuff" of value. My 401k is nothing more than an electronic account somewhere -- nothing actually in it. Kinda weird.
