Oh really? Specifically, which one? Give me a link. Keep in mind the latest inflation reading today was 3.33%y/y. This is also an optimistic reading -- if you use the exact same calculation the fed used back in the 80s inflation would be at 10% (many government obligations such as TIPS are linked to CPI and, as such, they are motivated to make that number appear low).

Risk free savings used to be much easier when the dollar couldn't be freely printed. Sure, there were times of moderate deflation and moderate inflation, but overall the average was 0. Furthermore, labor was able to consistently achieve wage gains. Those days ended in the 70s (and is evidence by the famous wage-vs-productivity charts). Also, you're conveniently ignoring the fact that fiat currency has made it possible for governments to print money to pay for war instead of needing to levy a tax on its citizens (something which would frequently be met with protest).
