This is one of those questions everyone wants to know - can I make upper-middle class income that will allow me to pay-off my loans. I have no comment.
I would recommend you explore your questions. What does "consistently does surgery" mean (and heck, what type of surgery does that mean)? What does private practice mean? Does that mean your own business? Because if you own your own business you are going to do whatever it takes to succeed and that probably doesn't include walking in at 7:55 and leaving at 5:01.
Anyway, I don't know about salary, but I'm sure there are people who want what you want and will get it. All I ask is that you don't blend all the things podiatry can be into 1 thing. I occasionally hear some variation of - oh podiatry, great lifestyle, solver of diabetic emergencies, and orthopedic surgeon-lite. I don't personally believes you can be all those things at once, but what do I know.
