I dont think there is any need to worry about health care because of Obama. The medical profession tends to exaggerate the cries of despair about how federal government universal health care will slash physician salaries dramatically and blah blah blah...
Due to the crappy economy and since it is based on the fundamentals of capitalism, I dont think government funding universal health care will happen until after we are all dead, if ever. Political change like this moves at a glacial pace and to create the infrastructure for this would take years. Universal health care is for socialist countries where extreme taxation on your paycheck happens before you get anything. Our form of "universal health care" would likely come in the form of multiple payors I think, which could actually be lucrative if you are savvy enough.
Heck, you can even make decent money now if you have a great knowledge of how to bill and have people you can trust in your billing dept. Document, document, document.
I think the most Obama can do is cover all children, and thats probably about all he'll get done, even if he gets two terms.
Honestly, I'd be more concerned about Medicare and their constant reimbursement cuts. Its getting to the point where PCPs cant survive practicing on their own between loan repayment, overhead and malpractice.
The physicians I know who work in underrepresented areas taking mostly Medicare/Medicaid patients would do better financially by going back to their local state college, getting an engineering degree and getting a job in computer or civil engineering. Because of the extra expenses physicians (PCPs specifically are hit the hardest) have, the engineer does better. I'm not kidding, I have a few college friends making ~100K after bonuses.
I hope no one thought they were going to get rich on their base salary.
