Destin's points are well taken but just to say that I'd have to see the details of this first. If this was something down the line, like in 20 years, whatever, so that people had time to prepare, then given extended longevity of living, I'm okay with some of these benefits being pushed back, not dismantled, presuming, as he rightfully notes, that people are able to remain productive, to be living satisfying lives. To save money immediately, I'd rather see the type of program I've suggested on other threads which is what others actively advocate, that Medicare be extended overseas where medical care is so much less costly than here in the USA. That this isn't instituted immediately is insane.
It's making especially more sense to me as I age because as we age we wind up with less people keeping us in place. The more loved ones you outlive, the more you wind up without any real reason to stick around where costs are such a rip off. It gets harder to justify paying more than need be, especially when you know you're getting scammed.
