The problem is that they have no incentive to actually cure. And near not incentive to provide cheap medication- which the patent system incentives you too, by running out after x Years. (Unless you are a frozzen Princess aka Disney) Lots of diseases are only researched at universitys. They have however a incentive, to sell anything expensive, to a audience desperate (that alone is a free market killer). And they do. I just try to understand how one can defend a held-hostage situation with free market rethoric.
