I want to know the answer to the following question:
Why are patents criticized?
All the background I'm provided with is that "In 2001, the WTO adopted the Doha Declaration, which indicates that the TRIPS agreement should be read with the goals of public health in mind, and allows some methods for circumventing pharmaceutical monopolies: via compulsory licensing or parallel imports, even before patent expiration.". Is that enough to answer the question?
Answer: no
