Gold Historically Outperforms S&P/Dow Jones

I’m no expert on the matter, but I find it odd that ever since the U.S government removed itself from the Breton Wood System (August 15, 1971), Gold has nearly outperformed the indexes.

Banks, Advisors, and the finance world in general have convinced the general public to never bet against the U.S dollar. “On average, the S&P returns 8-10%, it’s safe.” Etc. But what about the asset that, when left alone and not pegged to any federal reserve or monetary system, has flourished? How long will we put our trust in Fiat currency?

I’m curious to know your thoughts. It’s just been on my mind here recently.
