Short answer: your primary care doc is probably just as unhappy as you are. This article in Daily Beast is a great example of just how profoundly screwed up the American medical system really is. I'm constantly the broken record on here when it comes to doctors, I know, but it needs to be said: doctors don't like the system either.
Just the other day, I asked my wife, "Would you tell our children to pursue medicine?" and she didn't even think about it: "No. Never." No questions, no thought. Just an emphatic "no." There's something profoundly wrong with that, given that just a generation ago, medicine was seen as a great, rewarding profession.
Unfortunately, as much as most doctors would like to spend time with their patients, unless you're paying for concierge private practice medicine, you aren't getting more than your perfunctory 5 minutes. Too much paperwork, too many administrative tasks, not enough time in a day. Medicine is 70% paperwork, and 30% practice. This is even worse for those in internal medicine.
Frankly, the only way to win in the American healthcare system is to not get sick, or if you do, to be rich and pay for elective bullshit. The only doctors making money anyway are the ones selling services nobody really needs. The only people staying healthy are the ones who aren't sick in the first place.
Gotta love it.
