I don't necessary think there is an agenda to hold back the drug companies to find a cure...after all, they still haven't found a cure for the common cold. And new drugs and vaccines do go to human trials a few times per year..they just haven't been effective, yet. What does show some promise is gene therapy, the AIDS virus uses the same keyhole in the white blood cells to enter the body as the Plague (and the Plague is a bacteria). Decendants of Euroeans that survived the Plague and have 2 copies of the Delta 34 gene are showing immunity to the AIDS virus. Those with one copy of the gene will eventually get sick, but live longer and healthier lives than those without the gene. Africans, and people of African decent, do not carry this gene and have no natural immunity...part of the reason for the severe epidemic in the African countries. (I saw all this on PBS about 2 months ago - pretty facinating).
But we still have some problems in the US with "abstinence only" education becoming the norm in more and more US School systems. We are not giving kids the information they need. And before you start flaming, I think abstinence for teens would, of course, be an ideal situation, but in reality, Texas has one of the highest birth rates for unwed teens. They need to know how to protect themselves for STDs in general, of which AIDS happens to be one.
I have a friend who is infected, thank goodness he has health insurance. If he ever were to be without it, he could not afford his meds. They are nearly $1000 per month retail. AIDS victims without insurance are like the elderly, they can't afford their life saving meds.
