I'm impressed that your doctors can apparently diagnose a problem and prescribe something without seeing a patient.
They see us just fine. Walk in, get diagnosed, walk out, go pay for meds. Why would I pay the doctor just to write scribbles on a piece of paper? Honestly when was the last time a family doctor did anything more than write scribbles on a piece of paper?
You're not paying him to write scribbles on a piece of paper. You're paying for him to inspect you, use his decades of expertise to rule out problems until he's found the correct condition, and then prescribe a medication that works best for you given your personal and family history. Frankly, I'm not sure you really understand how doctors work. By your logic, you could scribble something down on a piece of paper yourself and get meds.
Why would i pay for that though? ---
