Or I can buy solar panels for the elementary school down the street and have them pay me 90% of their prior electric bill. The elementary school has a lower electric bill every month and I have a steady income stream and no one does any work.
And by the way, when you buy your bar of gold you pay some guys to dig some gold out of the earth and melt it into a nice bar. However I am not sure how the value and the price of a bar of gold compare.
