I think this is a natural outcome of a system where drugmakers can spend billions on advertising, marketing, and sales reps. Those are three activities with basically no ethical standards; their only job is to make the graph go up and to the right.

My solution: ban all of that. Let doctors learn about new drugs via means funded by the doctors themselves. Before the Internet, that would have been difficult. But now you can imagine specialist medical journals, or special AMA committees. Manufacturers would still try to manipulate that, but doctors wouldn't be grossly outgunned.
