He says buy farm land and productive assets will outperform gold in 100 years.
Partially true.
He failed to mention business is a cycle. At every cycle, some assets outperform the others.
You can buy a farm, in 100 years of time, you may experience great depression that many farmer lost their land. You can buy a farm that experiences dust bowl that caues soil erosion. Not to mention tax burdens over 100 years.
Same is for gold. Same is for stocks. One guys stocks that many if not most are not likely to survive in 100 years.
So the key is business cycle and super cycles.
