If you started with $10K in 1970, sure, the value is reduced by a factor of 7. Intentionally to incentivize investment.
If you started with $10K in 1970 and put it into the S&P 500, you'd have a 4162/83.15= 51X return, adjusted for inflation is still a 7X return. Notionally $510,000 - excluding dividends/re-investment thereof.
If you started with $10K in 1970 and put it into an average home in the US you'd have $70K today, adjusted for inflation. (Average $/sqft on an inflation adjusted basis in the US is the same now as it was in 1973 [1] - you'd have way, way, way more if you'd bought property in a major metro - I'm just being conservative).
You save value not money. The idea you should save money is a severe misunderstanding of basic economics.
It's really not that hard: don't save money, save value. Your narrative is as harmful as it is straight-up wrong.
