But the question isn’t really whether it’s got cheaper, the question is whether it’s risen sufficiently slowly relative to inflation that sufficiently low-risk investments can safely (enough) cover it over the long term. Getting much cheaper is sufficient for that, of course, but not necessary. Any idea how it looks from that perspective?
