Doctors' profession have artificial barriers to entry and keep the supply limited, in many other countries, but even with those, they won't dream to earn anywhere near 500k.
My cousin graduated med-school last year and is still unemployed because no hospital had a place for her. Private practices don't fix that issue since they're not designed to be part of the medical teaching cycle. So a lot of young doctors have to emigrate to other EU countries where they can find spots to practice.
