Interesting link, and together with this chart,
In 1850, one ounce gold worth $19, and until 1970, it still worth as little as $35, but in the next 30 years, it shoot up almost 50 times to reach a high of $1900, since the gold standard is abandonded. Is it means that everyone become 50x richer in the latest 30 years? Or something else happened
Another fact is that the gold price do not change at all after discovery of the gold in California, this is against the economy theory that sudden increase of gold/silver supply will cause inflation. Actually, since the USD exchange rate is fixed, discovery of new gold simply means new money, and that created a huge prosperity of the west coast area. Maybe it is from here FED learned that increase money supply can simply create growth without causing inflation, but they missed that new money must be debt free
