Said doctor should come to you, as is customary in many countries. Instead, in the US you have to drag your sick self in to see a physician. And pay a boatload for a 5 minute consult; ridiculous.
Perhaps videoconferencing could be a good option for simple cases (viagra, sleeping pills) while a medical pick-up system could be instituted for patients requiring in-person consultations, but lacking mobility or the urgency required for an ambulance.
Here in Uruguay, the lowest rung of doctors (which are the ones you get on call) are paid about U$ 1500/month. And they did at least 7 years of studies (which are tuition-free in Uruguay).
A lot of them are emigrating to Brazil of course.
It's not their wage that is important, it is the value of their skills and time. If two people must meet face to face, it is most efficient use of resources to have the least skilled person spend their time traveling.
