No, this has nothing to do with Obamacare so retract your claws.
I have for a very long time, as have many others, referred to physicians as "Doctors". However, as a college student who is now more aware of degree and the titles that come with them - I now know that a Doctor isn't necessarily a "Doctor" and a "Doctor" is not always, technically, a Doctor.
So here is a thread on a nursing site regarding their right as a nurse to refer to themselves as a Doctor if they have earned, through rigurous study and invested time, a doctrates in Nursing Practice ( A degree that allows them to act in some capacities as a physician)
Can you be called "Doctor" with a PhD in Nursing? - pg.5 | allnurses
An articulate quote from one Dr. Nurse -
Now this is a MD forum discussing the same topic. Skim through it if you like but the overall sentiments there are -
"No only we physicians get to be called 'Doctors'"

Now the title Ph.D predates the academic established field of Medical Practice. Being a Doctor of any field and referring to yourself as a Doctor was thing before physicians stepped into town. From what I can gather physicians in America, since outside of the US physicians are often referred to as just that physicians, started referring to themselves as Doctors to gain more repsect for a field of study that at the time wasn't being as respected as it should be.
Though physicians are skilled, vital, and educated people - I don't believe they have the right to monopolize the title Doctor, especially when many physicians do not have a Doctrates in the first place. Granted as language has evolved the word Doctor now includes physician as a definiton, but I don't believe that addition in meaning should trump the original and still applicable meaning of -
In a nutshell if you have a Doctrates in Economy - You are a doctor.
If you have a doctrates in English Literature - You are a doctor. And you have every right to refer to yourself by your earned titled.
