It's worth noting that if there are benefit cuts of 25% that it's unlikely that each individual will see a 25% cut. It's more likely (in my opinion at least) that we'll see some sort of means testing where seniors with other income (from 401Ks, private pensions, other savings) see their benefits cut much more than 25% while those with low incomes retain their full benefits.

So if you are saving a lot it could, ironically, be a self fulfilling prophecy that you get no social security.
