I do a GoodRx price check of every drug I see advertised on TV. There is typically no drug that costs less than $5k a month. Is there a problem here?
Of course, there's the problem of when companies make a 'new' drug that is very similar to an existing drug/generic that already exists. A great example of that in my head is how Cymbalta is not that much different than Effexor.
As a consequence, many large drug companies spend more money marketing drugs than developing them — https://www.raps.org/news-and-articles/news-articles/2019/7/...
