Let’s go to another universe. Let’s say that instead of humanity exploring the cosmos, they stayed on earth to perfect their crafts, explore the depths of the world, and complete it lifelong mission, immortality. But now the only planet is reaching it maximum capacity to hold human life. A new job must be in place to “regulate” the population. That’s where you fit in, you must find a way to help humanity before it collapse. Out of curiosity I must ask, what is your name? -- Anon Guest
Call me Ahab. I'm set on a mission to end white whales, so to speak. You know what whales are, right? They're the people who fund half of any given casino because they spend big. Most of them don't even know how much money they have.
Back in the Before, it used to be impossible to have that much money in one lifetime. You just couldn't do it. That was before one of them funded immortality. The select few could live forever and accumulate wealth. Unsurprisingly, pretty much all of the billionaires invested heavily in the research, and then the results.
Science cracked the mortality issue. It was never released to the public. Only ever given to those who could pay the highest ticket price to live forever. They claimed that the money would run out. They claimed that nature would find a new level. They claimed that the mind-numbingly rich would be good for the economy.
