@trashheap I understand the sentiment but I think it's dangerous to index anything on inflation, because it is a macro-economic indicator computed a posteriori. As a reduction of a myriad of past economic facts into a single number, it is entirely abstract and applying it to any real number is bound to have unintended consequences. What if this application feeds into itself? What happens when it's negative?
We are already treating inflation like an actual thing and not an abstract concept way too much to my taste, trying to drive it using levers that are almost completely uncorrelated from it like the national interest rates and reporting on it in mainstream news when it doesn't apply to anyone's actual situation in particular and doesn't help people make informed choices.
