I do believe I disagree with the sentiments of most of the replies. I think most of them are short sighted.
This "physician shortage" everyone is referring to is relative. As the government and insurance companies try to push through reimbursement cuts, they want to see as many physicians fighting over the minimal fees that they arbitrarily determine, like crumbs from their table. In order for this to happen, they have to convince medical educators to increase medical school enrollment and residency slots, and programs are responding unfortunately.
If residency programs across the board were as savvy as derm, they'd take a hint that the fewer docs in the field, the better the lifestyle. Do you think derm would be so competitive and yield such a great lifestyle if they kept opening more slots like most other specialties have over the years? Derm has limited the number of trainees, and therefore they control supply. Any field of medicine could do the same with greater or lesser degrees of success.
Pathology used to be a prime gig, but now they've over-trained and the field is saturated, forcing colleagues to compete for jobs and contracts.
My take on all of this is that there is only a "physician shortage" in the eyes of those who have to pay physicians. The more of something there is, the less value it has, pure and simple.
So what's going to happen? More med school slots will open, residency slots, and new schools will open, more IMGs will be admitted. The field of medicine will continue to decrease in overall quality because more students are admitted who previously wouldn't have made the cut. You will have to compete with these people for jobs that pay less and less because they are willing to work for less and less.
If you think I'm wrong, just wait.
