I assume you're referring to Social Security benefits rather than SSI (Supplemental Security Income). I know that some people refer to the former as SSI, though I'm not sure I ever figured out why. SSI is a more conventional welfare program paid out of the general treasury and for which a beneficiary doesn't need to have quarterly work credits.
That said, I think Social Security benefits will continue to be paid for quite some time. Politically it would be too problematic to get rid of the program. Even if we did at some point decide to do so, it would likely be a gradual transition out of the program - a transition that took decades to complete.
As it is the program has enough savings to float it for a while, and then we will have no choice but to make the tweaks needed to be able to continue paying benefits. With less people working to support payments to more beneficiaries, we will have to either raise the taxes some, lower the benefits some (or hold them steadier), or reduce the number of people that are eligible (e.g. by gradually increasing the retirement ages). If we'd make the necessary changes now they wouldn't need to be that large - just tweaks as I referred to them. The longer we wait the larger the changes will need to be. But regardless we will make them and Social Security benefits will continue to be paid.
Stick to talking about legal issues.
Social Security can not end due to insufficient funds. It cannot go bankrupt. It cannot be insolvent. It is a pay as you go system. Current tax revenue supports current retirees.
The funding issue that is looking with Social Security will occur in the mid 2030s (this has been well documented for a long, long time). The cause of the issue (also well known for decades) is that the demographics of our society are now negative. We have too many retirees and not enough workers to support them. Again, this is not new information.
Social Security will continue to take in revenues from paychecks. Until recently, revenues were more than payouts. The excess (aka the Trust Fund) was invested, BY LAW, (not some idiotic conspiracy) into US Treasuries. When expenses became more than revenues, the trust fund money was used to make up the difference. When the trust fund runs out all that will be left is the incoming tax revenue.
Current projections show that sometime in the early to mid 2030s, tax revenue will cover about 75% of promised benefits.
That is the reality. That has been the reality for a long time. This information is updated annually by the trustees and is publicly available.
The options to fix Social Security are relatively simple (compared to Medicare and Medicaid) but are not painless as the term "tweaks" insinuates. We need to do a combination of things, none of them palatable to a whiny, "me first and only" public: 1. raise the retirement age 2. increase Social Security tax 3. reduce benefits 4. Means test benefits (the wealthy don't receive Social Security) 5. adjust the COLA calculations. None of the solutions are earth shattering...they are the same ones that have been on the table for decades.
None of this is "news". Well I guess it is depending on where you get your "news".
a case of lagavulin single malt stashed for my 80th. Once that's gone, I plan on becoming a ward of the state.
:like: That is why we are moving out of Calvert so quickly. Daughter needs us to help with the baby, and we have to drive 3 hours round trip to visit. We have a contract on a house near her (will know soon if we got it), and ours isn't even up for sale yet, but, hopefully, by July. 
We will face a double mortgage for a while, most likely. You only live once. You can't take it with you, so go for it! Do what feels right. You and vrai are living your dream. Good for y'all!
