I’m pretty sure this story or novel is from sometime after 2000. The story features rejuvenation technology controlled by a corporation that demands all of their patients’ assets, every last penny, to get a rejuvenation. The company charges a minimum price in the millions of dollars, so only the very well-heeled can afford it. Of that few who can afford it once, only the truly driven can manage to start from zero and make a new fortune from scratch to afford their next rejuvenation.
