Question

Quizplus · Accepted Answer

The California gold rush led to a substantial increase in the money supply and a large increase in the Gross National Product (GNP), as well as significant population growth and infrastructure development. However, it did not result in a significant decrease in the prices of farm goods. In fact, the opposite was often true, as many farmers and ranchers left their lands to join the gold rush, causing shortages and higher prices for food in some areas.
