In the case of the drug, we as a society (and I use "we" very loosely here; in this case it means "mainly people who benefit directly from this opinion") have "decided" that a "person" (company) who invents a useful drug "deserves" to gain tons and tons of money, and operate in a way which prevents others from duplicating the drug, even if that behavior leads directly to the needless suffering of potentially millions of individuals.

In the world I want to live in, this type of thing would be given to society due to the benefits of it. "But it's an investment; how will they recoup R&D money?" some will say. My response is that we as a society should recognize that the "free market" approach here can be quite inhumane for many people and figure out a way to either publicly fund this research (and address the related problems such as fraud and embezzlement) for the benefit of everyone.
