In and of itself, I suppose not. (Although you do have to take significant 6-figure loans into consideration). I think the real point is that you can't very well expect medical students to want to do primary care when they know that their years of work will yield them less pay than something they could have spent 1/2 the time doing.
Think about this: A CRNA is generally 4 years undergrad, 1 year critical care (getting paid) and 2 years CRNA school. Say average pay for a CC nurse is $50K.... so they make 50K over their 7 years of training.
An MD is 4 years undergrad, 4 years med school, 3 years primary care residency. Assume average 50K per year during residency, total training is 11 years and 150K made.
Now you have to consider opportunity cost. The CRNA is making $190K per year for the 4 years that the MD is still training. That's $760,000, minus the extra 100K the MD made during training. This equals A TOTAL OPPORTUNITY COST OF $660,000 FOR BECOMING A FAMILY DOC INSTEAD OF A CRNA!!!! Then add in $10K more per year for being a CRNA over a family doc for a 40 year career - that's $400,000 more in earnings.
Again I will cap this because it is important. AT CURRENT RATES, A CRNA WILL MAKE OVER $1,000,000 MORE LIFETIME THAN A FAMILY DOC WITH FEWER LOANS AND NO PSYCHOTIC MED SCHOOL/RESIDENCY HOURS.
Now, please explain to me why any med student or for that matter any bright high school or undergrad student seeing this article would ever decide to go into primary care? Fact is, it's something I would consider except that I don't think I could stomach the cost. I will more than likely specialize, and probably enough so that I'll feel relatively safe from mid-level creep (ie, doing something with procedures that there is no way in heck you or anyone else would ever let a midlevel do on yourself or your family members). This is the unfortunate way that things are, and until it changes you will absolutely see no improvement in the primary care situation.
