It's an interesting point I'll have to think more on, and I hope Wade writes more about.
It's not necessarily the "I need the latest iPad" idea, as one could scoff, but the old idea of the government not calculating CPI correctly.
Normally I disagree, but the point about improvements not being counted is interesting.
Imagine a 50-year retirement, and you have 1960s standard of living today. It won't be that extreme, I'd imagine, but nor is it a "I don't care about the latest iGadget so this doesn't affect me."
It's yet another retirement wrinkle, that's all.
Thanks for sharing the link.
