Every time I start down this road (on paper) I find myself at the inevitable conclusion, why not just go to medical school.
Medical school only has a few more pre reqs and when you break down the schooling it's not that much more. PA is essentially 1 year of class room and 1 year of unpaid OTJ training. Medical school is 2 years of classroom, 2 years unpaid OTJ training, then 3-7 years of paid OTJ training. At the end of medical school (excluding the outliers from either field) the bring home earning potential of a physician is significantly higher.
Taking the earning potential out do the equation, physicians also get to do so much more in their chosen field.
Honestly, the only advantage that I found in my case of being a PA over a physician was the job change aspect. The PA is the only mid level field who can "do it all". If I want to slow down and work in a doctors office, I can. If I get bored of that and want to go work in the OR as first assist, I can just apply, etc.
Currently I'm still cranking my bachelors in public safety management out, once I finish that, I'll decide what I'm doing...
