I'm still reacting to President Obama's vision of overhauling healthcare.  Now that "Obamacare" is the rule of the land, I think that many people - maybe not today but in three or four years - are going to wake up to the realization that the way they used to think about medicine has dramatically changed.

First, a couple of simple facts.  There are approximately 209,000 primary care doctors currently practicing in the United States, and surveys have determined that in many states, there will be a significant doctor shortage by 2020.  Not only are populations aging, but population concentrations in many big cities are increasing, making the balance of physician-patient ratio difficult to maintain. In states like Nevada, Arizona, Florida, Texas, and Idaho, many people believe that there will be challenges in finding primary care doctors.

In 2008, one-third of physicians worked solo or worked in two physician practices.
