Funding for cure?

We often see news headlines of appropriation of large sum of money for a particular research, but is there a better way of achieving the final objective - namely to find a cure for a particular disease?

Take AIDS for example, there is absolutely no incentive whatsoever for major pharmaceutical companies for finding a cure. What would any company loose the prospect of making $13,000 per person on a triple cocktail treatment that essentially REQUIRES the person to undergo the treatment for the rest of the person's life. You do the math.

Instead, major cure breakthroughs are always made by a few so- called rouge research with their persistence, talent, and most import of all, ingenuity, that often get bogged down by major company. Why don't people, like the Gates Foundation, set up the monetary reward for finding cure, viz. $50 million for the person finding the cure for AIDS?

Just imagine how motivated financially scientists from academic settings and, in particular other countries who can often bypass the redtape of U.S. medical system, would get.

This reward system should be fairly easy to implement, even without support from major foundations. Take AIDS as example, with 36 million people who have it worldwide, it only require each person $1 to $2 to pool up the money, to be administered by the reputable entity, whoever discovers the cure is rewarded with the money.

Any thought on this?

Well, for one, because Bill Gates is not obligated to spend his money on anything. He sets up foundations that he and his wife are personally involved in. This goes for any other wealthy person or corporate exec. who wants to set up a foundation. Also, foundations have to meet certain guidelines. Many require grants to exist and have to meet the criteria based on those grants.
Another thing is that there are biological corporations who have patented genes. This means that if any researcher or research team/foundation wants to study a cure, they have to use specific genetic properties to do so. These researchers have to pay a fee to use genetic information for testing. Many cannot afford this. So....it's a stale-mate. There are researchers who have the knowledge and no money and you have the genetic companies who hold the patents and have the money, but will not grant access to them until the researchers pay for usage.
The only thing that would change this is to write your representatives and hope that there will be a law to change this. Good question.
