Affiliate Marketing Secrets

Now, I’m not completely firm with this, but I’m starting to think that cures for AIDS and Cancer and other diseases exist, but that they’re only saved for really important people.
Think about it. The last major disease someone important had was FDR with Polio, and they cured that. But when was the last time an important politician or some famous celebrity had such a disease?
Is it because of money? Is it the fact that marketing pills that will “treat” the disease insted of eradicating it will make more money?
To quote Chris Rock, “It’s like Cadillac making a car that can last 50 years. You know they can do it. But they won’t! You mean to tell me we can make metal strong enough to fly into space and keep intact when re-entering the Earth’s atmosphere, but I can’t have a Camero where the f**kin’ bumper don’t fall off?!”
So, any answers would be appeciated. And please don’t call me an ignorant douche. I’m not making fun of people with aids or cancer, I’m merely pointing out something I’m still currently deciding on.
