FYI: Both of these charts cover the period from 1939 to 1985. The first one is five-year U.S. treasury notes after inflation. Five-year bonds are thought to be a rather risk-free investment. You lend money to the government, you receive interest payments, and then you get your principal back. But one dollar invested in bonds was still just one dollar 45 years later.
