Not really. Gold is up about 10% over 10 years and CPI change over 10 years is about 27%. In the grand scheme of things that's flat. You forgot all the deflationary years in between.
10% is the best case depending when exactly you measure, but even then it's still actually lost 15% purchasing power.
Even against CPI, which must at this point be decisively regarded as fake news.
For example, apparently your TV is much better now than 10 years ago, along with your your PC etc, thus you're better off with the same $$, and so in theory inflation is lower by that 'hedonic adjustment'. But let's be real, you still need to buy a TV, and the market no longer offers 2012-era specifications at the same relative price. And the slightly -cheaper or stagnant prices of what is on offer, if we ignore meaningless specification inflation, are a result of everything getting crappier (Eg Ads built into the TV!).
Meanwhile DJIA and SP500 have almost doubled in 10 years, and almost everything essential; healthcare, tuition, housing, etc, has vastly outpaced 'CPI'.
