Humanity must deploy better systems to improve the longevity of the human race.
Money managers must improve the investment thesis that determines what returns can be discovered.
Economists, like Larry Summers, have a tendency to make shit up after a threat appeared unexpectedly in their rear-view mirror, for their modus-operandi is to deploy an extrapolation of hindsight sold as foresight to break the norm. Be forewarned, as an expert on ill-conceived consequences is merely a rebel without a cause.
