A more moderate view is that synthetic drugs are backed up by a LOT of research money and marketing muscle, and that marketing works. There is no conspiracy here, this is not a fatal flaw in our medical system, and the advice, and prescriptions, you receive from your doctor are sensible, based on good solid reasons, and have a higher probility of working than advice or medications you'd receive from some other health care worker (eg: a naturopath).
That said, it would be nice if natural (ie: non-patentable) and synthetic cures were on a level playing field. They are not. Patentable remedies are backed up by more research than non-patentable ones, more marketing material, a better information distribution system, etc., which makes it more likely that your doctor knows about them, knows what they're good for, and subsequently prescribes them.
That could be improved. It's not a conspiracy theory. It does not mean your doctors advice is worse than a naturopaths (quite the opposite is true), but it is something that should be fixed.
Of course fixing it is hard. The reason why synthetic drugs are better marketed is that it is profitable to do so, but the flip side is that research does pay for the development of really innovative new treatments that save and improve many lives. You wouldn't want to throw that baby out with the bath water.
So this is not a conspiracy, it's a policy problem, and it's not a simple one to solve.
