+1 Remember, "they" is us or at least our elected representatives.
The folks on this board are not, as a rule, representative of the "they" population at large.
Sadly a large fraction of the "they" voting on this stuff (citizens & their reps) are neither smart enough, planful enough, nor responsible enough to take responsibility for their choices over the long term.
I hate to say it, but I don't buy T-bonds or muni-bonds at this point in part b/c I don't broadly trust American culture or the political decisions it produces. Its selfish, self-serving, and in so many ways completely irresponsible. Look around...how many of your fellow citizens would loan money if they were personally responsible for paying it back?
Now, if I won't loan them money, why would I trust them even a little to care for my retirement?
This amoral herd will do whatever is best for them, in that moment. If it means screwing me based on some made-up pretense about my wealth or geography or because "the public unions were promised" this , or the baby boomers promised themselves sunshine and butterflies until the end of time and now I have to pay for it,then the herd will justify it to themselves on some pretense and move on. I will NOT trust these people to even contribute to my family's security.
So with that jaded, sad, cynical view of the my fellow citizens, I score SS at ZERO when I plan my retirement. Anything I do get back from SS is a bonus.
