There is room for a very limited number of people and supplies. For the plan to work, something has to be done to eliminate around 7.5 billion surface dwellers who are just "useless eaters" who will be toast soon anyhow. By around 2036 or so it will start to become obvious we are facing "disaster"...from Italian disastro, literally "ill-starred," from dis-, here merely pejorative, equivalent to English mis- "ill" (see dis-) + astro "star, planet," from Latin astrum, from Greek astron "star" (from PIE root *ster- (2) "star"). In the minds of the elite, they will be the saviors of humanity by murdering everyone but themselves.
