I always wondered this too. I mean, there are 170 med schools, right? Average class size is more than 100 for most. We'll just say the average is 100. Multiply that by 170, that's 17,000 doctors every year. I assume a very small portion don't get residencies or don't practice at all. But still, that's quite a lot.
Anyway, its obvious that pods will be needed. They've been needed since the times of ancient Egypt (supposedly). As the more-experienced folks retire, I see the field changing though. Residency training is getting much better and pretty soon we will have a lot of pods with good surgical and non-surgical skills. I wouldn't be surprised if it split into a two-specialty field, podiatric physicians and podiatric surgeons. I also would not be surprised if MD/DO's were given the ability to apply for pod residencies. I'm not interested in the money, so as long as I have enough for my family I'll be fine. It's okay, I'll pay the minimum on my loans for the next 30 years...TAKE THAT GOVERNMENT!
