For me, yes. It IS savings -- that money will be returned to you in the future (with interest), unless you wear a tinfoil hat.
But it is something you have little to no control over.
Because of that, I consider it a straight tax. Any tax is collected with the intent that it will be used to provide some return to society, and ultimately to the individual citizen.
SSI is earmarked to a particular use, but when and how much anyone receives is really open ended.
Will it disappear? Probably not.
Will someone who is 20 or 30 today get as much a return as the 'SSI annual reports' predict today? Also, probably not!
Its a safe wager that benefits will delay and/or reduce overall. It then becomes what % of the promised benefits folks are comfortable with assuming. Some say 0%.
I presume 50%. Regardless, everyone has to make it to whatever benefit age is in place at the time. If its 75 sometime in the future, I hope people don't get screwed by picking 67 for their planning calculations today.
