I am not OP, but upvote for the source. Just a note: graph does not start from zero, so growth is exaggerated. Current value compared to worst: 360$ (2019) versus 309$ (1981) - 16.5% increase in 38 years. Taking first value of the graph in 1979 of 335$ gives - 7.5% increase in 40 years. IMHO it's abysmal result. I hope this positive trend will continue, because if there will be some kind of downward correction - we will be back in 1979.
