Does the wide availability of pharmaceutical drugs contribute to a decline in personal accountability?

I ask this because my work in pharmacy leads me to question the necessity of many prescribed drugs.
I see several patients pick up Lipitor (for high cholesterol) along with bacon and eggs and packs of chips, or bottles of Metformin (an oral diabetic medication) and Methylphenidate (an attention disorder drug) with bags of candy bars.

My prescriber friends tell me that it doesn’t register with patients to be advised of lifestyle changes, everybody wants A or B magic bullet and if they can’t get a script from you, they’ll find another provider.

What does this attitude of “I don’t have to do anything, that’s what pills are for.” portend for the evolution of our species?
