The question is, if you are one of those types of dollar millionaires, do you feel rich?
Remember, money is the ability of energy to do work in the future… the further out in time you plan to spend it you have to project the world’s global energy situation at that time… in the US case, also the standing of the petrodollar.
… that nest egg you saved is not going to be there for you for the simple fact that the global energy is gone… the purchasing power of money was almost entirely inflated by the availability of cheap and abundantly high quality energy (and the work/productivity multiplier derived thereof) and the assumption that it would always be the case of remaining exercisable into perpetuity…..
