i think the root cause has more to do with under-regulation, regulatory capture and proactive efforts to confuse and blur the boundaries. Bad Pharma is a good intro if you care to move past entry level comments.
Haha. I have read Bad Pharma and I have been following Goldacre for years and I agree mostly with what he says. Please do not assume my ignorance just because I disagree with your view.
I fail to see where there is "under-regulation" in the pharma industry. Try setting up a Pharma business, you will be surprised how hard it has become.
