I would say this is all very much simpler.  Once we all know what psychopaths do to our society and what they are we will eliminate them from all authority with brain scans! http://cdn.theatlantic.com/assets/media/img/posts/2014/01/fig_3e_Jim_fallon_normal_vs_psychopath_PET_vs_normals_copy_2/1d4ff4ff3.jpg That would immediately end the pathocratic era that we have always lived under.  A new era of sane leadership would literally mean the meek would inherit the earth. That we would live in a paradise on earth by comparison.  The last book of the bible isn't called "revelations" for nothing.  Anyway how can the meek inherit the earth if we are all gone? It's an analogy of our progress as a species that we are raised up at that moment. We have made the next massive step forwards for humanity.
