A new car in 1971 cost about $3,500. That's 100 ounces of gold.
Today the average new car costs $49,275. That's 11 ounces.
You now need 89% fewer ounces to buy a car that's objectively better in every way. Safer, faster, and more efficient.
Gold didn't get more expensive. The dollar got cheaper. 89 times cheaper, measured in cars.
