Unfortunately it's almost true what I heard comedian Chris Rock once say about pharmaceutical companies today; "There is no profit in coming up with a cure!" The real money to be made is for coming up with medications that will extend one's life and allow them to (live with) the illness. TV commercials bombard us with medications to take for every itch and twitch known to man. "There's a pill for that."
Having said that I believe there are some very rich mavericks out in the world who do want to make a name for themselves as being "the person" who found the cure for AIDS, Parkinson's disease, Cancer, or Alzheimer's Disease. It seems like it's been forever since we saw an actual "cure" for something as big as polio was in it's day.
It was a shock to most people when Dr. Richard Sacra was cured of Ebola. It makes you wonder what else the government is sitting on.
