General Discussion

I think that in most countries with a universal healthcare system physician education is heavily, and sometimes entirely subsidized, as a public investment. Becoming a doctor, surgeon, or other specialist does not require massive debt or family money.

In universal healthcare systems, you don't generally have the sort of high-cost medical malpractice insurance we have here. Other models, such a government-backed indemnity system or "no fault" type system increases the portion of earnings the physician actually keeps.

Salaries sure look good to me, particularly when you get to start your career without massive debt, and don't have to worry about managing billing and other administrative costs associated with practices and systems here. Here's a comparison from Physicians Weekly:

All-in-all, physicians in universal health care systems appear to be highly respected people who make a very, very good living without many of the stresses and headaches the practice of medicine involves here.

Undoubtedly, they have different headaches, but looks to me like they are very well-compensated for the job and lengthy investment of time in training.
