Would they always need earth to be habitable?
Because if they somehow managed to terraform and colonise another planet like mars, wouldnt they just make earth so uninhabitable that the rest of us would be forced to go where they are? (Prolly as slaves)
Some may be delusional enough to believe that they can survive without the rest of humanity, but the irony is the billionare/epstein class benefit the most from society’s status quo being maintained (or the facade of stability being maintained). A nation’s currency has no value if faith in its institutions collapses after all.
