Having spent most of my adult life researching what it takes to become a doctor and deciding whether to pursue it or not...
They are not paid enough.
You do realize they go through:
4 years of undergrad (securing at least a university honors level GPA to even have a fighting chance of being accepted to med school) + insane amounts of extra-curricular achievement and activities + 4 years of med school + yearly board exams + 3-7 years of residency + 1-4 years of fellowships before they even become independent physician practicioners?
And you take like $50k out in loans for every year of med school PLUS undergrad.
If you graduate high school at 18 and go the most efficient route, that means you get out of residency at 29 if you're lucky. Residency also pays badly $40-60k for working 80-100 hours a week? Unless you're derm or pathology or radiology lol)
These people basically don't get their careers settled until their mid to late 30s. At that point they have spent over a decade of their lives slaving over textbooks and getting little sleep, eating poorly and living in constant stress over exams, riddled with debt, with parts of their lives on hold for their profession. Divorces are common in medical training. And they're behind everyone else who has had a chance to save money for a home, a car, a family, etc.
They often work graveyard shifts and spend their time tirelessly caring for people's bodies and rarely are properly appreciated.
And even with that large salary comes huge malpractice insurance and taxes.
Some don't get to start paying their debt off until their late 30s and sure I guess, congrats, you get to enjoy being wealthy and comfortable at the ripe age of your early 40s, after your youth is behind you.
This isn't even mentioning the politics and stress and bullshit that comes with interviewing for residency, hospital politics, especially clinic politics that are owned by some corporation.
It's not a sacrifice most people would be willing to do, and honestly the least you could do is pay them well for trading their 20s and 30s in for learning how to save your life.
Sure, neurosurgeons make $700k.
But you become a neurosurgeon at like 33 at the earliest. And you get it from doing a residency (which you only got into by being one of the best medical student applicants in the country) that is literally at least 90 hours a week of learning how to perform BRAIN SURGERY. And then over half your money goes to malpractice insurance and taxes.
