I'm really glad that you're asking this...it's like a self-exploration exercise regarding my future career 🙂 sorry, I didn't mean to sound like I was fighting ha!
For one, I think medicine requires more time and more debt to complete. This I think is unarguable.
Another thing, it requires much more work to get into medical school. Personally, I'm hovering around a 3.7 gpa right now, but I think I may very well do awful on the MCAT. And then the whole application cycle is pretty crazy argh. And then residency with 80 hour work week schedules....also, the academic work may also be more difficult in medical school compared to optometry school...
Also, medicine seems to be very stressful...though the job may only be a standard 40hr week, you will be dealing with a lot of stuff that you wouldn't be dealing with in Optometry. I twisted my ankle a couple years back playing competitive soccer. It was pretty bad. I had to go to the ER and wait for the em doc. I asked him if he could write me a note of absence from school and he told me he had no time because two patients were literally dying on him 😱 He also looked very stressed and unpleasant....obviously this is not the case with every field of specialization, but the stress is just there because mds play a vital role and are basically the primary doctors. I donno if I want to sign up for that.
I think these are the main points...as an md the pay is more attractive, but in the long run, the od has the opportunity of making as much if not more than the md counterpart....I know this because of my extensive shadowing with optometrists.
I have to go to work now so I'll get back to this thread later but I'll just add some quick points:
1. All those tax deductions you mention - you can easily do that in quite a few parts of MD... it's called
PRIVATE PRACTICE. Even as an ER physician, if you work as an independent contractor - you can label yourself as a corporation/LLC. You can deduct everything a private business can. From cell phone use to cars used for business (NO ONE can deduct an Ferrari... that's plain stupid and asking for trouble... meaning steep penalties and jail time).
2. Stress depends on the field. Yes, there are certain fields that are a bit more stressful than others but they're not all like that. ER (my field) may be particularly stressful at times, but those times also drive your adrenalin and give you a sort of "high". Other fields like PMR, FP, general IM, ortho, sports medicine (and a few more)... they are NOT stressful at all. No one dying really shows up to those fields (in general).
3. That thing about MCATs and residency and that whole crazy application process and med school? That type of a hurdle is what makes MD such a satisfying career choice. Like many of your attending optometrists say - it's not so easy to just pop open MD schools and have a surplus of graduates. The number of graduates is limited by the amount of residents the federal government (GME) pays for, the number of medical schools limited by medicare, and the gross difficulty of medicine in general (from MCATS to medical school to residency).
But what you get from all that difficulty is a niche.
Example, I was able to get 3 jobs (all high paying, more than 3.5x the average retail OD) in this recession market. All are FT jobs (not part time). And of those 3 jobs I got, I had a 100% success rate in the job hunt (meaning I really only pursued 3 jobs).
I think you need to really re-evaluate why you choose a particular field. Choose it not because it's easier to get through or get into, not because of tax reimbursements, or stress levels of particular specialties (since you can go into any other specialty).
Just my 2 cents.
