The problem is the way social security is funded is a ponzi scheme. The numbers don't add up, which means something will be done in the future. A part of the national debt it social security.

What the something is I don't know. There are lots of options. It is entirely possible that the younger generation realizing that the money isn't there will decide to scrap it. It is possible that taxes will be raised to pay it off. Maybe the government will borrow money to pay for it. Maybe benefits will be cut (this is already happening via inflation, but the effect is small). Maybe the retirement age will be raised. I don't know what will be done, but something will have to happen.

As you said, anything can happen in 30 years.
