I don’t think one should ‘do’ anything about it. It is simply an implication of one model of economic growth. On a personal level, equities are so much better in many ways that even if they would be outperformed by some hypothetical ideal ‘land’ portfolio, that you’ll be just fine investing solely in equities. (What must be avoided is stuff like cash, which won’t grow or benefit, or investing into fixed instruments like debt—if you expect any sort of takeoff soon with any probability, investing in a 30-year Treasury or something would be insane. You would want to be taking out 30-year loans instead!)
This sounds correct, though this also raises the question of what to do about it.
