Should More Money be Spent on HIV/AIDS?

I think that more money should be spent on the HIV/AIDS because, if we don't take care of the problem now,(in its early forms) then it will spread from nation to nation, country to country killing billions and billions of people. If that happens, however, we will lose great numbers in the population. Now, that might happen, and if it does there will only be a few thousand of us left, which means less and less stuff might not get invented for the future, education for children, on the other hand, will be having major problems with the government officials and other people. Humanity would be at one of its most horrible events ever.
