Pharma ads play a role but hardly explain this behavior. I believe a primary aspect is simply that Americans (including myself) expect and are expected to fill every waking moment with productivity or similar, rather than having flexibility to take a few hours/days/etc off to allow for healing and/or exploration of causalities; we instead use coping strategies and even with lackluster results continue down that road, seeking more alleviation of symptoms - initial, and consequential side effects from treatments for initial - rather than examination of root causes (which are complex and individualized to a large degree).

It doesn't help when others influence by saying "just take ... for that." I can't begin to explain why others do so, except that people generally have good intentions and are empathetic?

TLDR: Americans often don't invest the time and resources to identify and eliminate behaviors/conditions that are the cause of their ailments, and instead cope with any "quick fix" drug/product/strategy that never eliminates the cause of symptoms and often introduces new issues.

Last two thoughts: Many in modern society are very averse to discomfort - understandably, but regardless of degree/origin - and many doctors are happy to feed into this behavior instead of educating the patient that pain is sometimes a part of the process.

Many in modern society lack (or do not have the energy for) self-awareness and/or critical thinking to examine root causes of ailments/symptoms, and instead trust that taking ... will help without understanding the actual mechanisms/effectiveness of the treatment.
