What are the differences and the similarities in your opinion? Pros and cons .. go go goo
You go first. What do you think?
Also, some aspects of the answers may vary between different countries. For example, in the US, medical schools are expensive, so people studying to become medical doctors usually have to fund it by taking out large amounts of loans. They then spend the first part of their working career paying off $100,000 to $200,000 (or even more) debt. I suspect this is not true in some other countries.
On the other hand, again in the US, physics PhD students normally receive enough financial support from their universities to cover tuition and basic living expenses. They usually do have to pay for the bachelor's degree which comes before this, but so do the medical students.
I think that it is not only when compared to physicists, but when compared to all the other fields (biology, chemistry, math, CS, even engineering) a doctor in medicine will always be more respected than those. I think that is because of the "I save lives" motto.
