How much "later" do you have? you're 65, life expectancy is 76 IIRC in America. Worse depending on various socioeconomic factors. If I'm not living after some 40 years of labor what was the point of life?
Also, call me paranoid but I wouldn't be surprised if they tried to raise the retirement age like they did in other countries.
>but the assumption would be that the current pension still would pay out as it did before.
Does a frozen pension accumulate interest? If not, I don't see how the difference is ever made up.
