Why should I care if people are overprescribed pills? I'd much rather see people get the pills if they need them if the cost is overprescription than seeing people not get them for the moral reason of not seeing people get addicted. I never understood why society's role should be to save people from their addictions. That should be the role of the individual and their family, but mostly the role of the individual.
While I don't like the general concept of BigGov micromanaging everything they can think of either, the reason you should care is because abuse by professionals and experts who enjoy government support for their malfeasance is just an evil we should not, as individuals or as society, put up with. Well can't do lynch mobs to string up professional exploiters but we can strip them of their undeserved respect and pressure our supposedly representative legislators to curtail the abuse that is being tolerated because the pharmaceutical lobby is supporting an evil situation just to earn a lot of money from us personally and from government social support system.
