The cost of college education has been thrown around as one argument for alternatives. While I agree that college is expensive, and, perhaps, too expensive. What is your education worth to you?
To become a surgeon, it takes a hell of a lot more than following someone around and learning the technical skills. You need a strong background in biology, organic and inorganic chemistry, physics, and English (believe it or not) to name a few in order to handle the rigors of medical school which requires that you learn biochemistry, physiology, anatomy, pharmacology, psychology, molecular biology, histology, pathology, embryology and genetics (to name a few). You need a strong, well-rounded educational foundation to become, yes, even a surgeon. Remember, they are physicians not just technicians.
If you think that you can duplicate all of the biological, psychological, and chemistry laboratory experiments that are so essential to illustrating certain basic concepts and processes outside of college, you're wrong. Practically speaking, there is a reason why certain substances are only available to teaching institutions where they have specific certifications for dealing with and disposing of hazardous and radioactive materials. Don't forget the anatomic specimens involved in dissection. There is also a reason why those aren't available to just anyone. Beyond that, there is value in being taught by those who have dedicated their careers to the study of science, have conducted research studies, and have published in peer-reviewed journals. Who better to teach you the fundamentals of science?
College is not the only means through which one's abilities are measured when you apply for medical school. That is why there are things called a standardized test, letters of recommendation, extracurricular activities, and personal essays that factor into, say, medical school admissions. This is because there is no one single way to assess an applicant's qualifications. Everything has its limitations, so it is the sum of these factors that reflect an applicant's qualifications.
College is necessary because there is at least some measure of standardization in the classroom work of the basic medical school prerequisites. What this does is assure someone looking at your application is that your standardized test score wasn't a fluke but is consistent with your overall performance as reflected in your grades, letters, etc.
And, Dustin, knowing one factoid (or thinking that you do) that a physician "should" know but didn't can also be a function of having read inaccurate information on the web or in lay journals. I hope that you don't believe everything you read. I do wonder what you do read since you seldom throw out evidence to support your assumptions, declarations, and anecdotes.
I don't know the nature of your conversation with your dermatologist, but there are different classification schemes when it comes to acne. Some separate comedones (blackheads) from acne while some consider it a mild subset. She may have been correct depending on her background. There are things like that in medicine, by the way, in many fields. You don't always have universal agreement, particularly when it comes to categorizing illnesses, and definitions can change over time. So she may actually have known what she was talking about. Sorry to burst your bubble.
