Sorcha, keep it up! My children are also actively trying to prepare for their future retirements, and I'm trying to hang on to as much of my nest egg as I reasonably can in hope of passing some of it on to help with their retirements. Except for public workers (such as teachers--thank goodness for the teacher retirement system, in my case), most defined benefit plans have gone away, and SS is on a path to future insolvency. However, as you have shown, future retirees are not totally helpless. Now is the time to start saving for your retirement years. I and many other of today's retirees started saving years ago.
Of course, if the entire US economy tanks, which is unfortunately not a completely insane thought, we're all sunk. I try to refrain from political statements on this forum, but we simply must get the national debt under control. It Is truly scary. As most probably do, I have my own list of where to start, but we'll not go there. For purposes of AU, Amtrak is not at the top of my list.
On another note: No one burst my bubble. I was simply making the point that "the older people" as a group don't disappear; younger ones grow old to take their place. Whether future retirees have disposable income depends upon many things (see above).
And while my political side is showing: I totally agree that government's "management"--or lack thereof, is to blame for the SS mess. I believe it was during Johnson's term that the SS fund was raided to spend in the general budget, something that corporations are, correctly, not allowed to do. And it's continued ever since. SS benefits are a debt the treasury owes, just like other debt, imho. They took our/your payments (and spent them on other things) and they owe us/you benefits. It's not the fault of the current and previous SS beneficiaries, so no guilt trip for me. SS is, and has been for a number of years, totally mismanaged by both political parties. *steps off soapbox*
