My father, a military physician, retired from the service of his country and opened a private practice. I think he hated it. Not the patients but the whole system: insurance, drug reps, malpractice insurance, lawyers, and the rest of it. While stanchly opposed to "socialized" medicine, I think he liked being a military doctor (and administrator) better.

I remember talking with him when the government decided to allow pharmaceutical ads in print and on television. He told me it was a huge mistake. That it would make costs skyrocket and profits soar. Patients would want medication they didn't need (restless leg syndrome? Really?) and doctors would be pressured by the pharmaceutical companies reps (and personal profit) to give the patients what they wanted. The commercialization of medicine.

I never saw him happier than when he sold his practice and spent his days puttering around the garden. Young people would seek his advice about becoming a doctor and he'd tell them to seek another passion.
