is this the dumbest article ever? Why not zoom in over a week? or zoom out for 10 years? If the amount of gold to buy a chocolate bar in 1930 is the same as today, then gold is a terrible investment. Chocolate costs WAY less today than in 1930 (in 1930 dollars)

And since the price of chocolate (and gold) are HIGLY dependant upon conflict, climate anomalies, economy, and imposed economic challenges, you did the same thing with that comparison, you picked two data points that met your concusions. There is no reason to read any more of this article past the second paragraph.
