One thing to keep in mind... You're not paying for the ingredients in the pills. You're paying for the billions of R&D that's put into finding these ingredients. Some companies will spend billions on R&D in a single year. In 2000, Pfizer spent 4.4 billion, while GlaxoSmithKline spent 3.6 billion. This, along with marketing costs, are why generics can cost so much less than brand-name drugs.
Your numbers need to be adjusted to account for R&D costs by the companies which produce those drugs.
