Uniting the People

This quote from Robert Oppenheimer is interesting. Obviously, there is no precedent in human history for anything resembling this.

My best guess: regardless of the type of disaster, i.e., nuclear conflagration or environmental collapse, there will be plenty of survivors.  Say the average temperature of the Earth’s atmosphere exceeds 5° C above pre-industrial times, resulting in catastrophic loss of land mass, flooding, wildfires, famine, etc.  This would kill massive numbers of people, but not, in general, the world’s rich folks.
