They do experience piracy. Typically from nations where intellectual property rights are not well respected.
I'd say in the example of drug companies that's simply the cost of doing business. No amount of propaganda or lobbying for copyright legislation (domestic or foreign) is going to give one control over behavior of inDUHviduals in another country. (That's not the way successful legislation works...it is the way fascism works, but that's a different story.)
(BTW, who is Billy Tauzin???? Funny (as in "funny smelling", not as in "funny, ha ha") that he was on the radar of both industries we're talking about here.)
Look at it from another point of view: If what you're doing is "so revolutionary" then how is someone in Brazil knocking off your product in short order? Perhaps it wasn't so revolutinary after all? "Revolutionary"....perhaps that word doesn't mean what you think it means? (revolutionary != we spent a ton of money on it)
I think time to be realistic for drug and music companies: No matter how much you spend/waste on the drugs/artists you're developing, they won't necessarily be profitable or even worth it. Ditto for all the money you spend/waste promoting those drugs/artists.
U.S drug companies and commercial radio are both currently a laughing stock.
I'm going out on a limb here, but perhaps the drug companies should focus more on cures and less on treatments than they do today?
To me, they're ultimately hung up on Gilette's business model. Buy the razor (aka pester your doctor for the perscription) and they sell you new blades for life (aka you get some relief from your symptom, but e.g. your eyes will bleed the whole time). Likewise, music companies perhaps should focus less on what they think we should like/listen to (Clear Channel is an abomination in the truest sense of the word, and only the tip of the industry's iceberg) and more on what we actually like and listen to?
I'd also argue that drug companies make way too much money (yes, it's possible). If that weren't true, they wouldn't have as many problems selling their drugs. (Let's all recall our supply and demand graphs from econ 101....lower prices = more people can afford your product = higher demand) They -- like the music industry -- create their own problems, then do their best to blame others for the results (i.e. lobby the government for special treatment).
On another front....
Print publishing is a more interesting example to me. If they stay with print media (books, paper) they don't have the piracy issue (not really) but as the world moves more and more to digital and print publishing tries to follow, they suffer more and more of the related problems....such as piracy. Thoughts? Personally I still like to pick up a book when I want to read -- it's a very, very good medium -- but I'm going to be called old-fashioned for that before too much longer.
