We know that higher SES is an advantage. So, given that most physicians are in the top 5% of earners in America that does place physicans' kids at an advantage over many others. However, it is on par with kids whose parents are high earners in other professions.
We know that shadowing and jobs in health care settings are important. It would seem that doc's kids have an easier time of networking to find someone to shadow and many can find a summer job in a parents' office. Letters of recommendation from partners or physicians who depend on referrals from dear old dad might be easy to come by. This is an advantage but professors kids might have a similar advantage in getting lab positions or a big break on school tuition. Still, they are head and shoulders above the kid whose parents are teaching elementary school or cleaning the elementary school.
On the other hand, to whom much is given, much is expected. So, if you have all these advantages, you'll be expected to have made the most of the education you've been afforded, taken the necessary steps to do well on the MCAT, used your connections to do shadowing and volunteering and even working and so forth.
Advantage or not? Glass half full or half empty.
