I almost feel sorry for them. Not long now before they realize that their ponzi scheme is going to implode.
I don't feel as sorry for them as I do the younger generation. People who have lived their entire lives under a lie of unfunded entitlements aren't suddenly at age 60, 70, 85 going to say "oh well guess I need to get back to work it is the fair thing to do". No they are going to use their considerable power as a voting block to ensure they keep as much of what was promised. The consequences to the overall economy, the future of the country, and the quality of the life for the next generation be damned.
I am reminded of a TNG episode ( lol ) where at middle age all members of an alien race sacrifice their lives for their youth.
On a more serious note I genuinely do not understand why prolonging life past a point where quality of life is sufficiently diminished is a good thing. The smart geneticists agree and focus on quality of life over longevity.
But as long as we aren't turning grandma in to soilent green I think it's unlikely that working elderly is a realistic solution.
