I dont think that the practicing pods can answer that for you. You have to decide if the field is worth it using the salary figures the practicing Pods have graciously shared with those asking about the field.
What else will you do with a worthless undergrad biology degree and semi-worthless Biology masters with a low MCAT score? Especially so if your GPA is 3.3 and below and your MCAT is 500 or below. Pharmacy and Optometry are saturated to the point you might not find full time work, and Dentistry is just as hard to get into as DO school at least. PA and NPs might be another option, but you are also easily replaceable, and you do not have the final say on treatment options.
Podiatry, for all its faults, at least right now allows you to practice as an independant doctor with surgical rights of the foot and in many states up to the ankle where you learn actual skills that are hard to outsource. The only other people that can do your job are other doctors, and that is true for other doctors in thier field. Think about it, a Primary Care doctor's work can be done by another PCP, MD/DO and in increasing cases, PA/NP. Look at other professions and compare, even those not requiring a doctoral degree. Accounting can easily be outsourced, as well as computer software jobs and IT.
And these people that claim IT makes 120-150K are leaving out that most of these jobs are in high cost of living areas, and that the jobs are few and far between. Of everyone I graduated with in undergrad, the highest earner is right around 55K/Year (around 45K after taxes). People dont make six figures right out of college, some with college degrees will never make six figures. With Podiatry, I think it is very possible to make 150K, provided you are smart and work hard, which is around 100K after taxes.
To me, an investment of 300K at 7% intrest to make 100K/year for 30 years seems financially worth it, Podiatry or otherwise, but it is on the boarderline. You will have to decide if that is worth it to you.
