Ideas like this seem to me to be often based on a vast overestimation of how likely a drug candidate is to work. Something like 90-95% of drug candidates in the preclinical phase fail. And even if we go to the latest stage, phase III clinical trials, there is still a 50:50 chance that they won't work. Another issue is that the rich people likely wouldn't be happy with the chance that they're in the placebo group. So they probably would have to be guaranteed to get the real drug, outside of the actual trial.
