My point that I was trying to make is that it’s dangerous to assume that a commodity super cycle will last 20 years.   Some cycles have lasted for only 10 years, others much longer.  No one has a crystal ball to know how long this current one will last.  Maybe we get nailed for a couple of years and then it lasts for 5 years after that ending in 2016.  You are waiting for 2021 and end up the one holding the bag.  No one really has any idea, so to talk a specific year like 2021 it ending seems to just muddy the waters IMO.
