So, perhaps the solution is to be content with pulling in an income higher than ninety-five percent of your countrymen.
As an OD, you will certainly NOT be making more than 95% of your countrymen so I'm not sure where you got that figure. After paying your loans, if you borrowed 150K at 6.8%, you'll be making 60K per year, but you'll be paying taxes on nearly your full income since there's a cap on deduction for student loan interest. Sixty thousands dollars is nowhere near the 95% mark for income in the US. If you borrowed 200K, you'll be paying 18K per year for an income of about 57K per year....again, before taxes.
Now, 57K per year is not terrible, but it certainly takes the fun out of it when you realize you've gone to school for 8-10 years to be capped in the 50-60K income level for a good portion of your career, if not your entire career. The reasoning that points to "a passion for eyes," doesn't hold water since the vast majority of folks entering the profession now will be career refractionists - the addition of many, unnecessary new schools virtually guarantees that reality.
Honestly, no health profession is perfect; they all have their flaws and the future is unpredictable:
Dentistry: introduction of mid-level providers, recently developed products to eliminate a large number of dental conditions, the rise of corporate dentistry (yes, seriously), saturation in various metropolitan areas
Medicine: Decrease in reimbursements from Medicare/Medicaid, increased regulation and red-tape, HMOs, more medical schools opening up, push toward poorly-compensated primary care
Pharmacy: too many pharmacy schools, technology/automation of pharmacy, mail-order pharmacy, old pharmacists not retiring as fast as expected
As you can see, optometry is not the only field with a problem. If everyone thought like you, nobody would work -- too much risk, too many cons.
I'm not sure how else to say this, but I'll say it again.....No one on here has ever said that dentistry or medicine are perfect. Your line of reasoning is tantamount to someone claiming that HIV, the flu, and the chicken pox are all pretty much the same since they're all viral infections and people complain about the symptoms.
Dentistry and medicine, while they do face problems, are immeasurably more robust than optometry for a wide variety of reasons. While commercial forces have tried to get into dentistry, there's a built-in resilience that lies int he fact that you can't buy braces on 1800Braces. You can't buy a cavity filling on 1800ClassOneFillings, and you can't buy a root canal on 1800GuttaPercha. Get the point?
Medicine is certainly plagued by te insurance mess, just like optometry. Personally, I wouldn't go to medical OR optometry school now, even if I could rewind the clock. But if you do decide on an MD, your potential career options are infinitely wider than those who choose an OD.
So, you can say until you're blue in the face, that optometry, medicine, and dentistry all face similar obstacles, and you'd be right in that statement, but that's not the issue.
The issue is not what troubles they face, it's the effects that those pressures actually exert on professionals in the fields. That's what matters.
Just be grateful that you picked dentistry. In about 10 years, you'll look back on this thread and thank yourself for doing so. Be sure to buddy up with some ODs while you're in school. After you graduate, if you ever get bummed about the fact that your back aches (about the only complaint I hear from my dental friends), just call up one of the ODs you know and ask how their career is going. You might have to ask them to talk loudly on the phone since they'll have to speak over the background noise from the TV section, the lady handing out samples of little hotdog pieces, and possibly a Vitamix demo.
