I want to know the answer to the following question:
Why are these companies rewarded?
All the background I'm provided with is that "Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.". Is that enough to answer the question?
Answer: yes
