After World War I, the US federal government promoted increased resource removal from public lands at low prices to stimulate economic growth. This was done through the Timber and Stone Act of 1878, which allowed private individuals and companies to purchase public lands containing timber and mineral resources at low prices. The government hoped that this would encourage more economic activity and create more job opportunities, which was seen as crucial after the war.
