The Elysium is already here, it's just less separate than you imagine. The $100M and billionaire classes are quite good at wresting a higher standard of living for themselves, and naturally select for those who feel separate from and superior to the unwashed masses. They're not thinking they'll be dead by the time it matters, they are concerned about their offspring, they just know that their offspring won't be the ones suffering.

Large disruptions always create opportunities for a limited subset of people to do even better at the cost of everyone else doing much worse. The billionaire class is doing everything in their control to be in that elite subset, and so far they've been quite successful at that and there really isn't any reason in sight as to why their approach is going to fail any time soon.

Elysium is made out of people who live among us for as long as it is advantageous to them to do so, who can pay reputation consultants to keep the mobs with pitchforks away, who are pouring their money and influence into promoting a culture that makes everyone feel like the elite deserve their exalted positions and that if you don't feel that way, you're at risk of losing your chance of getting up there to be with them. And making us feel like that chance is real, it's just a breakout app away, and you'd better keep playing the game or you'll be driven into medical bankruptcy and your kids will get shot at school.
