I'm just gonna put this out there.
If you always had a roof over your head, you are privileged.
If you never went to bed hungry, you are privileged.
If you always had electricity, heat, internet, hot running water, you are privileged.
If you had parents who were literate, you are privileged.
If you are white, you are privileged.
If you had access to healthcare while growing up, you are privileged.
This whole "does being a child of a doctor help or harm your application" is a nonsense question. Of course it helps your application. Just by merit of growing up in household that is financially stable and educated, you are granted innumerable benefits - everything from increased likelihood that you have proper nutrition and access to healthcare, being in daycare rather than left with older siblings, being read to, being able to participate in sports and go on field trips, having all kinds of supplemental educational access that is not attainable for low income families. Not to discount that plenty of physician families are emotionally abusive or unstable in other ways, but that doesn't change that the majority of physician families are going to be healthier, live in better neighborhoods, have access to better schools and recreation opportunities, be encouraged to do well academically, be supported in whatever paths they pursue.
By the time you get to your medical school application process you've been benefitted in so many ways you don't even realize. THAT is where the privilege happens, not in the admissions process.
