I don't have a problem phasing out Social Security but I want every penny I've paid into it back with interest.
That's what will keep it going - the political risk of people not getting "theirs". Since you're paying it forward, and the money you are paying in is for current retirees and not yourself, the only way you'll get your money back "with interest" is if the system continues. However, if you'd be willing to stop collecting once the amount you paid in was collected, that wouldn't be too many years and it would help wind things down.
I don't see people lining up to volunteer, somehow.
I want a Ferrari Enzo.
And a Viper as a daily driver.
Guess which of us has a better chance?
